Subject: Re: LT1 to LT4 top end upgrade by rklessdriver on 2011/8/8 22:34:41 92 has a one year specific Opti harness with a 5 wire connector (the one thats is located under the fuel rail cover). You need to de-pin that 5 wire connector, cut off the shielded ground wire, tape it up in the harness and re-pin the other 4 wires into a new connector (Same order as they were placed in the 5 wire connector). EFI connection sells the 4 wire weather pack connector. Mike knows just whats up with these as he helped me a bunch when I did mine. If you are using a GM optispark, you will also need the Opti harness (from the fuel rail cover connector to the Opti Spark) that Caspers sells. No need if your using the MSD Opti Spark as the harness is built onto it. Will |
