Which terminal on the starter do I use for the auxillary battery connection
So I'm going to do the auxiliary battery like the police tahoes. I'm supposedly going to have to put the + cable of the aux. batt. at the same point on the starter where the main batt. connects to it. Im not very knowledgeable about these things, but I have found a diagram of the starter and I'm hoping someone can tell me which terminal to use, as I have yet had a chance to trace the main batt pos. cable to the starter b/c I had no idea where the starter was to begin with! lol! So thanks in advance!
There seems to be 3 places for possible connection of the aux. batt. positive. The 3 I'm speaking of are sort of near the center of the pic, about 10 o'clock position. I'm clueless as to which ones to use. If I had the parts on me, I could make a better judgement. Thanks!
The 2nd pic is one of the actual cables. And judging by the size of the positive cable termination, I might have to hook it up to the smallest of the three possible connections on the starter.

Threads I've searched on no one talks about hooking up the police setup. everyone else is using isolators.

It would seem to me that you would connect it to where the primary battery connects....
Is that cable long enough to reach the second battery tray and the starter?

Not sure if he doesn't know where the starter is if he should be messing w/ connecting a 12V cable as he might wind up welding something.
The answer is to hook it to the terminal on the solenoid that has the 12V cable from the primary battery connected to it.
Not sure why you can't connect it to the positive terminal on the primary battery tho. Either way the batteries will be connected in parallel and w/o an isolator, will both run down together.

I haven't paid any attention but if the starter is still on the psgr side as previous iterations of the SBC, then the cable in the pic doesn't appear long enuf to reach but guess you're about to find out. Good luck.

I'm just curious, but if you're wanting to have an extra battery, why not separate them with a solenoid so that you can control what the auxiliary battery does? You are doing a good thing by adding more battery, but what you're really doing is just making one really big one.
A well thought out setup will give you that same option, as well as being able to keep the batteries isolated so that if you do wind up with a dead battery, you can jump start yourself. I use this type of setup in my rock crawler. The main battery runs everything but the winches. The auxiliary battery runs the winches only. If I run the main dead with lights or whatever, I have a backup.
