One of the most common mistakes when upgrading or Nova's from a point ignition to a GM HEI or any HP ignition system is not changing out the resistor wire so the HEI will receive the proper voltage needed to operate correctly.
I did this today on a GEN 3 so thought I would share.
This is not correct and what is mostly found.
A resistor wire with a pig tail for HEI power connection sliced in.
Not a good thing! :no::no::no::no:
First you need to remove the engine wiring harness from the firewall.
This will be located between the fender and brake master cylinder.
Power brake can make this aggravating to get to.
Remove the 3/8 bolt and pull the harness away from the firewall.
Notice how the harness will separate so you can remove only the engine part of the harness.
Now you have the harness removed from the vehicle, you need to remove the resistor wire & terminal from the terminal block. This is a easy, just trace the wire and lightly squeeze the terminal and push and pull it out from the back side.
Now we make up the new wire.
you will need 24'' of a quality 14ga stranded wire (I prefer red in color)
2 GM specialty terminals NAPA part number referenced.
Use a quality crimping tool.
It is also easy to remove the factoy alignment terminal housing used on the HEI. With a pin tool you remove the housing.
Make up the wire with the new terminals and plug them back into the harness terminal block and HEI terminal housing. Re-install the wiring harness and your set.
Terminal for dist.
terminal for factory harness
Installing the factory harness terminal is easy, just push it in. and make sure it is locked into place.
PS: It took me more time to post and edit pics than do the work on the car!
