I have followed the directions I could find in converting my points ignition to HEI. First things first ... it fits and clears the firewall. Now for the wiring? What is this resistance wire I hear so much about and where do I find it? There was a single brown wire from the old dist to the pos on the coil and a single black (?) wire to the neg on the coil. do I re-use either of these? I can run a new pos from the fusebox for the bat terminal on the HEI ... but what do I do with the elusive resistor wire.
one wire should have been going from the neg of coil to distributor. the other wire went from pos of coil to fuse block. this was the resistance wire. check it for voltage in run. if it shows less than 12v, it is still a resistance wire, and you need to change it to non resistance, or get 12v from somewhere else for your hei. if it shows 12v, follow it and make sure no one has added a ballast resistor. if there is one, remove it.
My 69 had a black with pink stripe wire running from the fuse block to the pos if the coil. I removed that wire from the fuse block and replaced with 10 or 12 guage copper wire. Works like a charm!
Thanks for the help guys .... here's how it went. Ran a new 10 ga wire from the heavy pink ignition wire on the column straight to the distributor. Picked up Accel Super coil, cap, rotor, and wires and installed the whole works. Turned the key ... NO SPARK. 12.8 volts constant at the distributor so Pulled the module. Figured what the heck and changed it out for a new one. Turned the key and runs like a charm - No looking back. I definately recommend this swap! Quicker response and better starting. Is it me or does it really wake your engine up!
