Default Wiring A/T to M/T 02-03 WRX

Ive already done the hard swap. The trans and motor are back in. I have the shop manual for diagrams but i cant seem to find ALL the definitive answers to my questions.

Where exactly is this manual ID pin i keep reading about?

how do i connect the NSS to the clutch?

ive already read IluvDrt's post and its very informative.

The pin was for the GC/BG/BH era ECUs. GD and newer don't have to worry about that pin on the ECU.

There's a very good and descriptive thread on one of the Forester forums I found when doing my swap. However, due to some chewed wires I ended buying a dash harness off eBay. iWire also sells an AT to MT wiring kit. I had bought that before finding the chewed wires. Might still have it kicking around if you want to buy it. PM if you do and I'll take a look for it.

Update: I was using the wrong connector at the bulk head. Progress has been made.

The grey plug, not the black. I hooked up the Neutral position and brake lights to this. The car will turn over by the key... if its in gear. Still wont start tho.

Reverse lights work.

the fuel pump only seems to kick on if the the key it is any position but start/run.
fuel gauge reads empty ( its a full tank)

Ebrake light stays on all the time.

still wrapping up small bits on the manual swap.
I still have to connect the rear struts.
The fix i came up with for the cultch line failed so i ordered the OEM clutch pipe from Subaru, instead of a short brake line from oriley. it did fit but it has a small leak... go figure.

Unfortunately snow_bound26 had the DCCD IWire kit. I'm gonna order the one i need. At least to get the clutch safety back in action. I guess a speedo wouldnt hurt. Even tho i prefer to use GPS on the Radio. Not to mention clean it up and make it functional.

I'm making small bits of progress in my free time. I got the cobb sf airbox in. O2 sensor in. found a new way to route all the wires and hose for the gauges through the firewall. got the DP and AFR back on. Wired in the oil temp/pressure sensors for the gauges. I got the radiator in, just need a new clamp for the lower rad hose.

I think all that's holding me up is a main relay and a clutch pipe.
Not sure how i could have fried that relay, that's a concern.

After talking with Snow_bound26 i think we may have figured out how i blew the relay. I jumped the starter from the battery to the tab the trigger wire goes to. Makes sense now.

wasnt the main relay... i think the ecu isnt getting a signal from the ignition? Could the TCM be blocking the signal?

Removed the dash. This wasn't nearly as difficult as I had thought. Removed the old harness. I started feeding the new bulkhead harness throughout the car, it goes in a hell of a lot easier than it comes out! Going to finish up the rest of the wiring harness today and see if I can get it to start...

Let us know what happens. What did the harness cost?

i got the harness on ebay for 380 to the front door. unfortunately it didn't solve the problem.... but money well spent on an intimate experience with my car tho. now that its done correctly and no splices and everything is manual. Im starting to think its not the trans swap and something happened during the procedure.

Something....Somewhere is crossed.

Here's what its not.. New/used bulkhead from an 03 MT and known working engine harness from a previous motor i had. New main relay. Two different ecus. the new bulkhead had all the relays and fun stuff plugged in, i reused my security box and immobilizer. added ground going to intake manifold to battery. used the shop manual to locate every ground.

when the key is out/off and i connect the battery the obd2 gets power and the scanner tool will turn on.
turn the key to acc and the power cuts the obd2 off
turn the key and it cranks...
turn the key back to off and nothing.

with the key off.. if you turn the head lights to on the scanner plugged in the obd2 kinda powers on but not fully.
The fuel pump (wally 400) makes a faint click every couple of seconds, also when the key is out/off
I was quadruple checking the grounds under the hood... heard a faint buzzing. followed this back to the alternator. i unplugged it. started the process all over again, turn the key to see that the battery light in the cluster goes out. but stilll yet again no progress. You guessed it the key was off.

This is like the 3rd motor ive put in this car, now suddenly, im having a weird open loop i cant for the life of me find.

im gonna unplug the engine harness and see if i can start to narrow something down.

i cant find anything in the shop manual showing me the headlights/multiswitch tied into the ecu or obd2 or anything systematic

please for the love of my sanity someone help

I would start at ignition switch. Not that it's the problem but check the wires going in and out for power and grounds where they need to be.

You have power at start position. Something weird is happening in run position.

I had a similar problem with my mr2 turbo swap. Ended up needing a ground at main relay. Added ground then she ran good for next 10 years.

Isolate and brake down into sections rather than trying to hunt all over
