instead of paying for a used ignitor and coil that will probably go out just like the one i had or paying 300$ for a new one i opted for the "easy" gm conversion . like seabass did but instead of using a 1000 ohms resistor and the stock coil i bought a coil for a 1973 chevy truck 350 v8 (or any round coil with negative/positive terminals on it) (11.99 autozone) and a "ignition module" from a 1985 chevy k10 350 v8 truck (14.99 autozone) .

your igntion hot wire (or any hot wire if you wanna have a toggle switch hidden some where) goes to the b terminal on the gm ign modu then from term b run a wire to the positive term on the gm coil. then run a wire from the c term on the gm ign mod to the negative term on the gm coil. then the g and w term on the ign mod go to the two wires coming out of the distributor cap. just use trial and error hooking them up, if you hook em wrong it will idle real high and fast rough, if you hook em up right itll run perfect. theres only two wires so its 50/50 not too hard.

soddering would be best on all the new connections along with grease, also on the bottom side of the gm ignition module is metal that is your ground to bolt it or wire that to your old ground on the fender .

anymore questions feel free to pm me

My last Toyota ignition module lasted 300,00 miles.
When I drove GM trucks, I didn't go anywhere without a spare ignition moule in the glove box beacuse they failed so often. I'll spend the money on a Toyota one. JMO

I'm with Zags. If I wanted Chevy reliability that's what I would have gotten, and I would still get the parts from a GM dealer, not AutoZone.

the reason the gm mods went out so easy was becuase they were under the dist cap where they got real hot, with this method you can mount it in the glove box away from heat and water and i bet itll last a long time. besides this way youd have to go through about 20 gm mods before costing the same as a new toy one. plus you can stop by any auto parts store and get one for 15$

you also gonna pay 300$ for a spare to keep in your truck for when yers goes out on the trail? or a 15$ spare?

Ummmm...did you use dialectric grease on the bottom of the module and mount it to some sort of a heat sink? The module's what makes the heat and the distributor base is supposed to be the heat sink. If you didn't you'll be buying another one soon.:p

mines still in the "fix it so i can get home" stage so its dangling not touching anything with a wire connected to it bolted to the old ign mod mount for the ground, so itll cool down quicker i would think


oh well for 15$ imma have 3 spares in my glove box :flipoff2:

im gonna wire it to under the dash so i dont have to get out :flipoff2: or even leave my seat for that matter :flipoff2: and along with the gm 1 wire alt ill basicly need two wires to run my engine. one hot going to the gm ign mod and one from the alt to the battery

something goes out ill know exactley what it is , even if they dont last as long as a toy im sure itll last long enough for the simplicity of the system to be worth it all. i hate wires :mad:

What a great idea,I wish I had thought of
that...Oh wait,I did,some years back on
the off-road.com site.The GM ignitors dont fail if you use a heatsink.I've had one in my 68 Volvo for 11 years.
The best coil to use is the Accel Super Coil
model 140008.This coil has the correct
input resistance of .5 ohms.The GM ignitor was designed for this load.Also if
the Accel coil is use,you can safely gap
your plugs at .045.I run mine at .040 to
go easy on the rest of the ignition system.

Looks like they not only attached a heatsink, but a fan too. Interesting...
