pj 90 gxl

My engine seized in October of 2001. I got an 88 parts car with a rebuilt motor three months ago. I finally got the enigine in and running, for the most part. It still needs a tune up and lower radiator hose. Needless to same I am happy. The only problem I have left to figure out is a black connector under the intake. I used the vacum, and fuel lines, and the wiring harness, and intake from the s5 engine, and the rotor housings ect from the s4 engine. The conector looks similar to the o2 sensor connector. If any one knows were this connector goes or what it is, could you please tell me. I will try and take a pic of it and post it tomorrow.

All in all the engine swap went fairly well. I only worked on it for about 2 hours on weeknights and three to four hours on sat. So as you can imagine it took awhile to pull both engines and swap the intake and vacum lines to make the s4 work in the s5 body. The only engine code I am getting is for the engine temp sensor, but the gage works correctly. I have most of the 88 left for parts if anyone needs anything, the trans. is a 5-speed but I think it may have some problems, I never drove the parts car. The body panels are basically trashed and so are the seats. The glass, suspension, rearend, wiring harness are all good. I am also considering selling the 90 once I get it 100%.

Thanks for all your help along the way.
