2000 Ranger - unknown connector under dash

Not sure I can do all 4 in one post but here they are

It shows which fuses are key on/off and which are on the same bus

Update:

Continuing to probe the fuse box - I found fuse positions 1 (power mirror switch) 7.5 A, position 5 (not used), and position 9 (brake position switch) 7.5A are all fed by the same wire through a localized buss bar. The vehicle does not have power mirrors, so total load across these three positions is 7.5A.

So, current plan is to use unused "key on" circuit 12 to trigger a relay through a fuse tap, and then use position 1 as the power feed through another fuse tap since the vehicle does not have power mirrors.

Sound logical or crazy?

Ron D -

So, just printed these all out and took a look. Basically, I think I was on the right path looking at fuse position 1-5-9. The are on the top of the second page you sent.

Short story - these feed to the Maxi fuse under the hood through the tan/blk power feed wires with a few others on the same buss. The vehicle does not have power mirrors and the cigar lighter is basically GPS only. So, I should be more than safe tapping into this main buss for power feed. I will probably drop the cigar lighter fuse down to 10 amp just for good measure.


THANKS again!! These helped me validate what I had been deducing with my VOM.

The Maxi Fuse(125 amp) is for the alternator, alternator powers ALL electrical systems when engine running
So Maxi fuse is connected to ALL fuses in one way or another
