Could someone describe where ALL the body and engine grounds are located on a 97 XL RCSB 4.2?

 

Seems like a lot of work.
Challenge Accepted!

 

G100 Lower right rear of engine, on starter motor mounting bolt
G101 (4.2L) Rear of engine compartment, right side of cowl panel
G102 (4.2L) Rear of right fender apron
G103 (4.2L) Right front radiator support
G104 (4.2L) Left front radiator support
G200 Lower right cowl panel inner
G201 Lower left cowl panel inner
G202 Upper left cowl panel inner
G203 Lower Right Kick Panel
G400 Left rear of frame

 

Awesome! Thanks for the quick response. Would you know if there is any behind the dash or something specific to the headlight switch and or blower motor? I cleaned grounds G101, 102, and believe 103 (battery ground and 2 others on one stud) and headlights, signals, and cluster still don't work when turned on.

 

Instrument cluster, main light switch, blower motor resistor plus about a dozen others are on G203. Give that a try. I got that # off another diagram though, so the number might be different. But it's in the lower right kick panel.

 

G203 was the culprit if my problems. The head of the bolt was rotten and didn't exist and the wire was broken off from the looped connector. Made a new one and relocated Lights and heat all work perfect now, I was starting to have doubts lol. Thanks for all the help it's well appreciated I like my new to me truck that much more now

 

Hey! How did yall find the ground number locations? I'm looking for 201 on an 03 f150!

 

The links don't work, BUT, pretty good, so far I only see 3 missing.

 

Thank you sir!

I'm having issues with 2006 f150 and I was told they found a bad ground in g202. Where is that located on this vehicle, if you're familiar? Thanks in advance.
