the problem im having is the dash connection's for the ecu i just need to know how to wire it in, im also looking into getting a 90-92 ecu for the 7mgte, m/t. this way i could use it with my 91 harness, but if i guess right there will be connector's on the 88 block and head that wont work with the 91 harness... im stuck in a dark place... lol... HELP
