ok , i have a vacuum advance distributor for my carb setup in my 90 camaro. i am not using any of the old wiring harness, as this is a mainly drag setup. on my dist. it has a plug that goes from module into the bottom of the dist., now the only thing left is spades, one for BATT and one for TACH. can i just run a wire from my batt straight to the BATT spade on the dist and one from the TACH spade to my aftermarket tach? i am eventually going to use a msd 6al, but right now i just want to get it running. also, when i do switch to msd, do i have to bypass the ign module? thanks in advance!!!

 

You can't run the "bat" terminal straight to the battery. It needs to be a 12 volt switched source. Run it off a wire that gets 12 volts with ignition on, and make sure its a nice thick wire, 10 guage or so.

 

im going to run a basic switch panel with a mom. switch for starting, can i just wire it to a switch , then to the battery?

 

The switch would work fine. You could wire the bat terminal straight to the battery but the car wouldnt shut off if you did that. You need three things for a car to start. You need to get rid of one of those three for it to shut off.

 

You should have kept track of the wires off the original distributor. One mine it was a tan wire for the tach and a semi-thick red wire for the batt. I just cut the ends off and spliced them to an HEI-style plug thingie. If you hooked the dist directly up to the battery you wouldnt be able to shut the car off.

 

thanks guys, the car was gutted when i bought it, so i am just basically working from scratch here. i am running elec fan , dist, starter. should i use relays for all of these? i hope i can figure out the headlight and brake lights too, i do wanna drive it on the street sometimes as well. there is no fuse panel, so i am confused on wiring the lights, blnkers and brake lights. thanks again!!!

 

Yeah the wires came in the same loom still together coming from the drivers side,
