I'm having weird electrical issues. The car has been sitting for a few years so I'm just trying to get everything solid since its my DD now. The PO had some wacky electrical fixes. Plus I never changed the voltage regulator when I got a new alternator before I stopped driving.
I'm just trying to fix shotty wiring from PO and make sure everything is reliable. And seeing that one prong isn't connected and one prong has a splice in the wire before it reaches into the cab had me wondering if this is how its suppose to be?
Appreciate the time and help thanks
OK , GOOD !
your in the correct skool of thought here for sure , don’t waver from the making it all OEM correct mindset approach , you can’t go wrong here especially if a DD now …
I added the red ink to keep the focus points in check here :
- the missing wire is your IG / it should be a white wire w/ red tracer stripe
- the F Tab goes to the F terminal in the back input plug of your FEN connector on the back of your alternator…
The single tab stamped E is earth or ground
White wire w/ black tracer
As I see it as you describe your odd electrical issues have

% to do with this absent IG wire ?
The scary part is that is the KEY ON signal B+ voltage ?
You should check your fuse box , in-fact if your glass tube fuses look old simply go to a marine store like west marine and just replace ALL of them period !
This will eliminate any possible chance of a good looking broken inside filiment ,,,,
I say marine because there stainless steel end caps and will NOT corrode like the China

crap ones at auto zone will or be bad out of the Cracker Jack .25 cents packs they sell
Look for BLUE SEA choice systems brand best bang for your $19 bucks to fill up your fuse box the best possible way other then old color keyed ones from japan
Below are tech pics to help you along and set you up for sucses
Remember !
Do 1 wire at a time this way you won’t melt down your wire harness to ashes …
