Thanks! I have an aux battery in my K20 - wanted to confirm that K5's could also be so equipped from GM...

The relay doesn't mount to the inner fender in the OEM set up. It mounts to either the tray or rad support - can't remember exactly which but certain it isn't the inner fender. I'll see where we mounted the relay on my K20. Here's a pic that shows the J-block on the fender:

If I remember correctly, it mounts to the core support, next to the regulator. If I had my assembly manual, I would look it up for you, but its at home...

That is where I put mine when I installed the aux battery.

My '72 Jimmy had the center rear belt, but it was not on the SPID. It had AM/FM and cruise control, and that was not on the SPID either. We got it used in '77 so previous owner may have had dealer add?

It has aux batt tray now, but I added that.

Just looked at the aux. tray, does have holes in the side, but none seem to line up exactly for the relay
