Default engine wire harness HELP...
Ok so I have a 94 trans am lt1 4l60e with a tore up engine harness. So I got a replacement out of a 95 Z28 Camaro lt1 4l60e. On the trans am I have 25 wires going thru the firewall into the car. But the Camaro harness has 22 does anyone have any idea what the other 3 wires could be. They go from computer to inside car. Any help is appreciated

95 was obd1, 95 was obd1 with a obd2 connector. take pics and post up the ones you have questions on. also, c200,c210,c220 all change 'slightly' year over year, use shbox site to do a lookup year over year.
