I have a 70 Malibu with a newer sbc 350. The HEI gets 12v from a blade on the fuse box.

I was wondering how to remove the resistor wire terminal from the engine side of the fuse block plug? I have another harness from a 71 to practice on. I would like to use this terminal to supply 12v to the HEI module.

Hey DG,
You don't have to cut your harness if you don't want to. Just run a new wire from a switched terminal on the fuse block, or use the resistor wire to operate a relay thats connected to a non switched terminal like the horn relay. mgg (Gold # 209)

Hey Manny Gomez,
It is not like my harness hasn't been hacked on before. But if I can remove the terminal from the engine side of the firewall plug, I'll just reuse the same terminal using a non-resistor type of 12 guage wire. Looks neater that way. I might be able to figure it out, but I remember someone asking about it on this page.

DG,

I cut the wire about 1/8" away from where it went into the connector on the firewall side and soldered in a new wire, then I melted some black plastic around the exposed solder job and it looks like factory.

DG;

You can simply remove the wire with the spade connector from your terminal block. Just slip a small piece of wire un the "plug-in" side (for lack of better explanation) and release the retaining tang on the spade connector. At the same time tug the wire and connector out! You don't even have to try and re-use it! Just go down to your local NAPA or whatever and get a small bubble pack of new GM terminal connectors. They cost about 69 cents to 99 cents and look like a regular spade connector with one side cut and sort of sticking out to act as a one-way retainer! SAME AS STOCK AND VERY CLEAN!!!

I did this swap on my 73 by getting a stock HEI feed wire with the spade from a 76 Malibu. This slipped right into the resistor wire slot. Of course I had cut the wire at the junk yard and had to splice on the coil conn, if you take the whole wire, it will already have the coil connector on it and be about the right length.
Don't forget to remove the R wire from the starter.

73Malibu, why is it necessary to remove the 'R' wire from the starter? Would'nt this just parallel the non-resister wire from the fuse box? Would'nt hurt anything if it was left on.

When I first put in my HEI, I retained the "R" wire from the solenoid to the coil, this melted through the jacket after about 2 weeks, and almost burned my car up. Stock HEI cars do not have a "R" post on the starter. The "R" post sends full bat voltage to the coil for starting with the points ign. Don't know why my wire melted but it is not required anyways.
