Engine wiring help
I need help temporarily wiring my motor to start it. The wiring in the truck is a mess and I am trying to get the engine hooked up so I can see if it runs ok. I know the heavy positive battery cable goes to the starter (already hooked up). The s terminal on the starter is the one I hook to my switch to engage the starter? Also, a positive wire goes from the battery directly to the distributor? That one I just disconnect to shut it down? it's a 75 or 75Impala 350 with an hei distributor. Is that all I need to know? Obviously I'll wire it up to the ignition key when I permanently hook everything up, but I just want to test start it to see if it will run.
Thanks!

Re: Engine wiring help
The small starter terminal closest to the block says "S". That is the start terminal. Go from there to the battery through a momentary switch to start. If you have an HEI, all you need is a good 12v source from battery to the distributor cap. If you don't care about the alternator, that's all you have to have to make it run.

Re: Engine wiring help
Don't forget the negative cable to the engine block

Re: Engine wiring help
There's a battery ground cable run ning from the battery to the alternator bracket. Do I need one to the engine block as well?
