Subject: RE:94-94 1/2 optispark? by BillH on 2007/12/27 16:01:56 Yea, the pin assignments on the 92 are the same but the wire colors are different. Here's the wire connections: 92 LT1 MSD black/red(stripe) to brown/yellow - low resolution purple/white to brown/orange - hi res yellow to red - 12 volt black/pink to red/green - ground The 5th wire in the LT1 harness is a ground/shielding wire. It's not needed on the MSD Opti. It doesn't connect to anything on the GM Opti either, just wraped around the other 4 wires for shielding. |
