I found the wire config. Cut and pasted from Tyler's (tjpreul) older post: I ended up hard wiring mine in. Here is an answer from BillH when I installed mine. "I need to add on the 92, unless MSD made a change recently, the opti connector will fit a Caprice harness but not the corvette. This isn't a big deal, just 4 wires to solder and heat shrink. 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." Note: On the shielding, I left mine off too with no problems in 4 years. One person has posted that they had a problem until they has that shield connected to ground. But I'd try it without first. |
