OK I have a couple of questions concerning the TFI upgrade for an 88 GW. There are 2 wires coming out of the old coil, one yellow, one green. Which one is (+) and which is (-)??? Also on the yellow side of the coil there are 2 wires. One going to the wiring harness the other going to a small cylinder I am assuming is a resister. Do I need to hook this resister up to the new TFI coil or can I leave it out??? Thanks
