Some people like to call it the big 3. I call it the big 5 because I don't like to take any chances.

Here'* what I need to know from anyone who has done this before. How much wiring, in feet, do I need for:

Alternator
Battery ground to block
Battery ground to chassis
Battery power to starter
Battery power to accessory block

Thanks!

15 would prolly do it but 20 feet to be safe

You will likely need to measure the distance to the battery under the back seat
then double it !!

Sorry, I should have specified. w-body.

IMHO its looking like 15-20 but then you still have to go to the trunk ...

Right. Just wanted to know for a friend who already had all the amp wiring done and needed to upgrade his engine bay.

Pop the hood and take measurements

I would if it was my car and if it wasn't 10 degrees out.

10 degrees?! Psssh, I wouldn't be doing that either!

I hear you there. It was 6 degrees out the other day and i was out messing with my stereo. Wasnt fun
