GM starter wiring question

OK, Im not real bright when it comes to wiring but I bought my self an EZ Wire kit for use on the 39.

The question that I have (the instructions are not clear enough to me) it shows to run the "Ign Sw Start" wire to the prong closest to the motor and the "Solenoid PWR" to the prong closest to the frame ( I think anyway). The drawing is unclear on whether it goes to the prong or to the post where the battery connects. I believe it is the prong though. Started looking at my new mini starter and it only has the prong closest to the frame. HELP

Doc here,

Your description has me a bit Cornfuzzled too...However, If I read it right, your looking for the post that the "IGN Start" wire goes to on the Solenoid?

If thats the case, Your solenoid should have a "I" or it, (that's for secondary ignition) and a "S" marked on it..(That's for the Solenoid energize...or start function..) It sounds like you want the "S" terminal, if you are looking for the place to put the wire that has power on it when the key is all the way in the start position.(to make it crank)

If it's non HEI..or HEI wired through the fuse panel or other non direct source, you will require the "I" terminal also..It provides power to the coil during cranking cycles..(the key shuts off power to the car's electrical system in the start function) This will provide power during the cranking cycle to the coil.

The Only other wire coming off the main bolt on the starter terminal should be the fusible link...providing power to the fuse buss, and alternator.

Doc

I cant figure it out either. I have two wires but only one post. The post closest to the frame. Wiring diagram shows that the solenoid power (Red wire)(secondary power I guess) goes to this one. Dont know what to do about the Ignition Switch Start Power wire (Purple wire)

Wiring

Doc here,

You should have one 10 gauge wire with a large ring terminal on it. This wire should go to the main Terminal on the solenoid and fuse link.

The only other tab then must (by process of elimination) then be the Ignition Start power Wire..

Apparently your solenoid does not support a secondary Ignition line...therefore you'll have to either ignore it ...or hook up a relay to energize the relay coil at the same time the solenoid is engaged..(should you need a secondary Ignition source)

If you can scan and post the schematic I can better help you out.

Doc

Bingo Docvette, I just got off the phone with the starter supplier. He stated the same. Solenoid power off the main battery post on the starter to energize the fuse box and the start wire to the only prong. THANKS FOR THE HELP

Thanks for this thread! Solved an UGLY issue for me... I just want to clarify for future readers because I read and re-read this MANY times before I got it right... Basically, wire that was on R goes to now single post and what was on S is now on main terminal (battery pos)... Doc, your awesome!
