Default Another swap

So I got my car running last night.

Right now I have a EJ205 engine (out of my 02 WRX) in a 1998 Impreza.
Instead of finding a WRX harness somewhere and splicing it into the existing harness, I just bought the ECU connectors, the engine harness connectors, and the other accessory plugs like the boost solenoid, front o2, etc.

I think I paid $50 or maybe $75 for the connectors, and then about $100 or so on wiring supplies and built the harness myself. I spent about 3 hours labelling all the wires on each connector and the wires I needed from the RS harness. I spent about another 8 hours or so connecting things together to build the harness and then connecting the RS stuff to the harness. I spent some more time wiring in the fuel pump controller. I haven't really cleaned up much of the wiring inside the car and I still need to put all of it in some split loom.

The car started perfectly the first try. What made the wiring so easy were these solder splice connectors from Tyco. They are inline connectors that have a ring of solder in the middle, with a sealing ring outside of that, and then heatshrink after that. With a heat gun and about 30 seconds you have a soldered, heat shrunk, sealed connection. And once things are shrunk, the size is virtually the same size as the wire, no need to splice things staggered, etc due to bulk.

The car is being built purely for autocross, there are lots of other things going into the car, at some point when it's done I'll document everything.

The car:

The harness:



Inside the car:



The engine that will eventually occupy the engine bay:

Right now it has no motor, that's why it's just sitting out in the parking lot and I'm driving my truck.

I will hopefully be swapping the engine back into the WRX this weekend, so I can start daily driving it again.

What that a 98 RS you started with? I think I saw some ABS lines in there.

Why did you do that? There were so few Brilliant Red RSs to start with.

I can understand your pain since I use to own a green Unicorn myself. I have never even seen a Brilliant Red 98 RS even for sale.

Where did you get the Tyco connecters from? Sounds like you had a good idea. Can you take a picture of a connector and of a soldered connection so I can get a good idea of what it looks like and what I might be looking for in the future?

Thanks

Wow, where did you get the connectors from? An individual party or a business? If you found a way to locate connectors, that could be a real tool for those who are having a hard time locating harnesses. I would have considered that myself when I was looking for my harness. Which connectors did you buy, B134-B137, B84, F60, 62, and B2, wastegate plug, o2 plugs, and did you find the FMU plug? I bet others would really like to get this info!

Thanks for sharing!

Well I got them from IA Performance, they are from a V8 JDM STI. When an importer gets engines, they get cut harnesses, which include the connectors most of the time. Either that or they have leftover JDM bulkhead harnesses which have everything attached. All the connectors you need are the ECU plugs, bulkhead-to- engine harness connectors, MAF, Front/rear O2, EGT (if your really want it), and boost solenoid.

I didn't have the FPC connectors, I just soldered the connections directly to the FPC pins.

I agree it would be great if someone could source the actual plugs and pins, but I have no idea about getting bare plugs, etc.

The car was salvage car that had been stolen. The front fenders, rear quarter panels, etc. had been bashed in with a bat or something. The replacement front fenders and hood were already white. The guy who painted it kind of wished I'd left it red, but I like white. It's not a great paint job, it's a race car, I got the car fixed and painted for a lot less than what you'd pay for a good paint job. The car has a junk title and as such can not be driven on the street...legally.

http://www.raychem.com/US/datasheets...lderSleeve.pdf is the datasheet for the connectors, they have pictures. I originally got them from newark.com but later got them from allied electronics.

hey quick ot question... what brand of radiator hoses and other hoses are you using? that looks like you have a perrin short ram intake (like i have). i'm trying to match my engine bay to that color; are those all perrin hoses, and if not what are they and where did you get them from?

Those are samco radiator hoses, Perrin intake.

As sort of an update, I've decided to mount the ECU under the passenger seat. The wiring is just a little too long to coil around and stick under the ECU kick panel. I'm running a Hydra ECU which is a bit larger than the stock ECU (and has its own extension harness), so it'll just work better that way.
