I have the EVTM’s (Ford factory wiring diagrams) for all my Fords
These manuals are approx 100 pages. The pathetic wiring diagrams in a Haynes are 5 or 6 pages.
Guess which manual actually gives you the detailed info you need to fix this simple little problem and your next electrical problem.
Enter the info for your Ranger at helminc.com & at the pull down menu click on “electrical troubleshooting manual”
I just checked & the manual is on sale for $14.00. It’s worth 10 times that.
