I am putting a 99 engine into a 2003 chassis (99 was wrecked in the rear, bought a 2003 tub w/ intact dash and lots of misc wiring under the hood, etc.), and want to see if I can use the 2003 engine harness, since the blue "power" plug (non-ecu plug that connects the engine harness to the rest of the chassis harness) won't plug into the 2003 chassis plug, plus there are about half as many wires on this plug on the 99 as the corresponding 03 plug.

I laid the two engine harnesses out, and there is only one plug that the 99 has that the 03 doesn't (a single wire clip on plug, not sure where it goes yet), and one plug that is slightly different, it is 2 pins on the 99 harness vs 3 on the 03. My other alternative is to pull both dashes out and swap out the entire chassis harnesses, but I'd like to avoid that if possible.

So, does anyone have an 03 wiring manual, or have any experience with this?

 

Oh yeah - I have to get the car inspected for the rebuilt title, so I need to get it running N/A with the 99 ECU. Then I will be swapping over the turbo parts and modding the MS in the 94 with Abe's board (or selling and building a DIYPNP).

Thanks Stephanie!

 

That this is illegal under federal emissions law? You can't put an older engine into a newer car (legally). You may not be able to get the car titled at all. Even if you do get it titled in Indiana you may be unable to sell it.

 

Indiana law allows me to do it, so I'm not worried about that. I am not planning on reselling the car any time soon, so the decreased resale value is not a problem.
