You know John, it always catches me a little off guard on just how much you dare to be different! Please, in the name of all that is holy, DO NOT do the "Ron's Nissan" wiring job!!!!

John,

What is your plan for converting the wiring? Are you keeping the RS harness and adapting in the necessary WRX parts? Have you documented which wires/connectors need to be added/removed?

Anybody else think it's a bad idea to be doing this while drinking beer and watching TV? What would chapstick think?

To answer a few questions, this will probably the best documented swap EVAR. I am using the RS harness for everything not related to the engine, ie lights, gauges, EVAP, HVAC, etc. I am using the WRX harness ONLY for the engine and ECU (stock WRX ECU) and mating the 2 harnesses together. This involves taking 2 WRX harnesses (Dash harness and engine compartment harness) and cuting out about 75% so that only engine related wiring remains. It's no small step to make that first cut on what's probably $1000 or more worth of harnesses, fortunantly I got em cheap. (thanks Hondaslayer!) Once the WRX harnesses are "pared down" to only the engine / ECU section and spiced back together, I have to remove the sections of the RS harness that control the engine. I will than have to integrate the two harnesses together... for example the WRX ECU will control the stock RS EVAP purge control solenoid through the stock RS body harness, by splicing circuit B134/2 from the RS harness to B137/16 at the WRX ECU.

The wiring is not for the faint of heart, but I am planning to document this well as in pictures of the harness routings, what is cut out and left in place, and most importantly, a cross reference for what circuits from The RS harness get spliced to the WRX ECU, and diagrams for the more complicated sections, like converting all the diagnostic connectors to work with both the RS ABS / SIR systems and the WRX ECU.

Hope that answers your questions... it's been fun so far, now back to drinking and cutting.

P.S. don't worry about the drinking... it WILL run the first time I twist the key.

Technically you twist it, turning usually implies a lever, like a window crank

That's my story and I'm sticking to it!

Thank you. Finally some light might be shed on this subject. No more i-speed "trade secrets". The only bad part is I have 1998 and the wiring is quite a bit different. But once again Thank You.

Ya, you're right. Twisting implies imparting a torque which is what you are doing to the key.

a key is a lever, just with a short fulcrum...
Twisting implies deformation of the object being twisted (a lemon twist, do the twist) turning implies rotating an object. i'll have to go with turning the key

So I guess it'll start the first time I deform the key.

yama - nice.

It's good your documenting every step but what about when the manufacturer changes looms or runs into a problem with a certain loom and has to substitute one loom for another to keep the production line running without stopping (not that I'd know anything about this... ) or they cut costs and change the looms mid production???

GOOD LUCK and please try to start the car up on a Saturday when I'm back in MI visiting.

OH...I don't have paypal. Can I write you a check from the bank of Ugonda??? I think I've got like 34443532555 bazillon dollars in my account there...atleast that's what the email I got said.

Great job yamarocket630 ! It's nice to see other people taking up the challenge and actually figuring the wiring out. Are you documenting the time (hours) each task is taking...like seperating the wiring from what you need vs don't need or actually soldering time?
I am curious to see how long it would take for someone doing a first time conversion. We, unfortunatly, drank to much beer, walked away frustrated, and didn't track any time for the first conversion. We did eventually build have a 6ft beer pyramid. The base was 45 beer cans

[quote]Finally some light might be shed on this subject. No more i-speed "trade secrets". QUOTE]
I tell all the people the same things about the "secret"...thoroughly review the manuals and figure it out.... ahahahaha that's the big trade secret everyone complains about. Honestly itís no secret. It just requires work. And unfortunately, yes, each MY has itís own little SNAFUs, which = more work

Again, great job yamarocket630 !

Yeah, the wiring has been fun... here's a quick pic of thr nearly finished harness... it's about 16 feet long!

first off:
I can't believe you guys are argueing twisting vs turning (looks for nerd icon)

but second...

dayum, looks like so much tedious (sp) work! I woulda broken into a seizure and started to bleed from my ears after trying to do that

Can't wait to see the install photos

Yama-

Ever think, once you've gone through the headache of figuring out your harness, you'd like to do this for everyone else on the board that is doing a swap? It seems to be the one thing holding half the people up on doing a swap. Right now, the only solution is to learn to do what yolu are doing, or if you are close to someone who does swaps, pay fat $$ for them to do it. I see a nice niche where you could make some $$. Sure, go ahead and document it, and post it. But I can tell you right now, I'm not even about to attempt to follow that. I'd rather throw you my harnesses, and get then back plug and play.

BTW, I get a 10% marketing fee.

I kind of like the throwing fat money at me thing.


Update, things not going as planned...
The flywheel fits my motor but not the clutch... it seems I got a flywheel for a newer WRX engine and the bolt pattern isn't the same for the pressure plate as the older engine.
The engine crossmember is bent! this puts a major damper on the plans, as now I have to source another one...$$$ oh, well, like they say if you have to ask, you probably can't afford it... and I have to ask.

on to the weekly eye candy... a WRX/RS hybrid radiator... the WRX core (almost double the cooling capacity) with the RS top and bottom tanks that mount the radiator and fans correctly to the vehicle.

Simply pry back the tabs that hold the tanks on (carefully!) remove tha tanks and swap them, Compress the gasket underneath the tanks, tap the aluminum header back straight with a hammer and retension the tabs.

we did a little work last night.....

test fitted WRX sedan control arms :-) to bad they stick out WAY to far. did everyone know that a wrx wagon shares the EXACT same lower control arm as a GC car! So i have a bit of old school aboard my wagon!

as for the cross member....new one will be here for this weekend.

Special thanks to smilin john at hodges for the smokin deal on it!

work will resume this weekend & hopefully by late sat / early sun the motor will be in the car and all we will have left is wiring.

Hey John,

Yes this answers my questions. Thanks for the information and hardwork on documenting for the subie cause. I would recommend putting a paypal "donations" button on the top of your reference page. Heck I would be willing to send some good Karma your way when I need to use the information.

If you left some of the dash WRX harness in, would you be able to adapt the WRX cluster (would it even fit) ? If not, I wonder if you will have any problems with RS guages not quite working properly with the WRX sensors and ECU.

Maybe you already answered this, but how much did you get all the WRX parts for to do the swap (if you don't mind sharing)?

-Rob

Again, i must say.......you are without a doubt THE most anal person i know, so i know this will be a "factory" job when completed. on that note, when ya gonna bail that stock turbo? If you remember our recent phone conversations, i have located said parts for project "2.5 ES", and will be in the market soon for goodies. by the way, i think i want to stay with original plans with horn i'll be the only one that'll know ( besides you)
keep me posted, and good luck........P.S. , FINALLY got that job i've been waiting on for over a year now........WOOO-HOOOO!!!! Beer @ cost!!!!!!!!!!!!!!
