hello,i did a b6t swap from my 91 capri xr2 into my 86 323 1.6i the 323 was already fuel injected but i used the engine harness from the capri and the ecu. that being said the car runs some what but it wont rev past about 2500???? the only thing im wery about is the long black plug thats next to the ecu. the capri ecu/engine bay harness side will plug into it but the wires dont completely match,some do some dont and the capri side of the plug has 6 more wires,but the car runs just having the rev problem???? i thought i would ask on here to see if anyone has had this problem, i probably could figure it out eventually but im being lazy lol need a quicker fix lol please help if anyone has any info on this,thanks
