Has the factory label been removed? They are usually taped to the main section of the harness. That would be a really quick way to tell what you have.

 

What color is the first wire on connector A (the grey ECU plug) on the harness. It has 9 wires in the top row. If you have an 02-04 harness it should be Black/White and if you have an 05 harness it should be Red/Blue.

 

Im relaying the info to the person who has my harness. I know Ryan at rywire also said the tsx would have 2 extra white plugs. So hopefully I got an rsx harness.

 

Easy to tell the diff between tsx and type s that's why I posted the difference between the 02 and 05 :up:

 

Well I asked my buddy to look for the extra white plugs that Ryan said would make it a TSX harness and he did not see those.

He did tell me the grey plug had blk/white so I am assumign I lucked out and got the correct harness afterall. I will post pictures once I get it to verify Im not missing anything.

I hate going thru this all the time with this project. I mean it should have been done in the first place another way and wasn't.

Thanks for the feedback guys.

 

I have one right now and the biggest notice i could say which is a huge difference is this triangular shapped box that connects to the fly by wire on the tsx. You can't miss it. Unless your blind others don't have it. The more settle differences are the 2 little wires on the end of the fuel rail connecter bracket they aren't on the tsx BUT ARe on RSX. Also the ecu connector for the rsx has like 1 long connector like 3 inches and tsx just has 3 smaller ones. Peace

Your problem sounds like you did not hook up the main relay correctly. It feeds the fuel pump relay coil, the eCU and the radio.
This schematic is very good to orient yourself on what it needs to run.
