Online source for electrical connectors

Thanks Lew for the link. I haven't been for a long time, PM me next time you go, if it's on friday, It'll be next week before I can make it.

I think what I'll do on my car is list the electrical loads, then make a wiring diagram. Hopefully on the web somewhere is a "typical" diagram for a drag car that I can modify.

If you find a diagram, please post a link.

K&R Switch panel kit has all labeled wiring, connectors, heat shrink tubing and tie wraps, and is worth the money. They also have a wiring diagram if you need one.

Thanks Sean, I'll post what I come up with, should be starting in a week or so.

No offense meant, but you don't have to buy any "kits" for something that simple.

3 schools of thought when it comes to wiring GM starters. First is do it like the General designed. ARC recommends wiring like this and has their panels set up with high amperage switches. The downside is GM used 10 or 12 ga wire since the solenoid got hot and amperage draw went higher. This usually doesn't play well with micro switch most shifters use for a NS switch.
Second method uses either the old style or new style Ford solenoids. You use a heavy jumper on the GM starter solenoid and use the Ford solenoid to switch the main battery cable. this allows a smaller wire as a trigger since you're using the Ford solenoid as a relay and it doesn't require high amperage and you can mount it in a cool spot. Down side is with a permanent magnet starter motor it can at times cause starter run on and you have another set of contacts and voltage drop to the starter windings.
Third method is running the main cable to the starter solenoid with no jumper. Use a heavy duty relay or a Ford solenoid to switch the solenoid trigger wire. this way you have low amperage through your starter switch and your NS switch and then run a 10ga wire from the relay/solenoid to the starter solenoid.
They all work.

"No offense meant, but you don't have to buy any "kits" for something that simple."

I prefer to source my own components, relays, fuse panels, junctions, wire, cable, etc...and put the system together as I like. Forget finding anything worth using at the typical auto parts stores.

We prefer #2. Just one cable to the starter and nothing is hot unless the starter is engaged. The solenoid can be mounted at the firewall out of harm's way or inside with a pass through or quick connect.

Pay attention to the ground circuit. It's at least as important as the power side.

Thanks for the additional feedback. I'm still working on installing the engine, trans, etc, so I haven't really focused on the electrical yet. I have done everything in building this car from a rustbucket to a stocker, except paint and machine work, but for some reason the electrical part is my least favorite. anyway, it's a 70 challenger, 383, denso mini-starter and alternator.
