| MAF to MAP wiring ?
| just swapped an 87 TA to a MAP setup. removed old wiring harness and using a stock harness from a 92Z. problem is the pinout for the 4th connector (not attached to the ECM) is laid out different than the 87 harness. if anyone has a wiring schematic or has repinned their harness to work with the stock plug it would help me out tremendously. i got the car to run and can read data streams through the ALDL by trial and error but can't get the check engine light to come on and go into diagnostic mode. i can't get the fuel pump prime circuit to work properly either. any insights or comments are appeciated. | | |
