Just got a 1998 ek. Its got a d16z6 swapped in it from a 93 del sol. My problem is this:

The shittiest wiring I've ever seen. The whole harness is f**ked up. The ecu is the p28 for the motor. My question is, could I just buy the engine harness for the d16z6 and the ecu and just have the car obd1 or should I get the harness for the car itself and keep it obd2. Cause right now I have a check engine light and when I hook a scan tool to the data link it reads no link and I tried doing it obd1 way but it doesn't work either.

 

just use ur p28 ecu and wire up vtec

 

So you bought it that way? And you're bitching about it? Are you sure it's a P28 cause that's the correct ECU for that engine.?

 

Yes I bought it that way. I didn't know the wiring job was so shitty. All I want is to clean it up cause it's a giant mess.
