Here what I got and car tries but wont fire. I have the heavy red wire going to the big post on the starter where the pos cable hooks up. (Battery is in trunk) I have the heavy black wire going to one of the starter bolts. This is my main ground. I have a 4 pin HEI that I removed the moduel from and the condenser as requirered. I replaced with the long orange and black wires that run as a harness and pluged them into the wires harness that ran to the one side where the moduel plug into. (cap) I plugged the orange wire into the neg. side of the coil followed by the ground in the middle and the black on the pos prong on the coil. I put nothing on the prong that said battery or tac. I then connected the smaller red wire to the wire that use to run to the cap marked battery for my 12 volt swithed power. The direction said to just tape off the final white wire caused it is not used with the HEI. Whats wrong. Please help.
