Here is a picture of how I tapped into the coil packs neg. coil drive signals which are yellow/blk , green/blk , and blue/blk on my 86 .The J&S Vampire yellow,green,and white wires go to those 3 wires in any order. The Red wire of the Vampire picks up 12v+ off the solid blue wire going to all 3 coils.Because of lack of space and wire between the coil and the module and John and I decided to cut off and install new flag terminals using them as the splice. After hard wiring them in I wanted a way to be able to unplug the unit, so I made a small 12in harness with male and female disconnects. The J&S Vampire Kit wasn't hard to install,the trickiest part is working with 27 year old wires. Do to lack of time and bad weather ,I haven't been able to test drive and adjust the sensitivity. More pictures and the complete install to come , just wanted to show how I did the wiring.
