Help with physical locations of grounds

[dragstart]

Just got a 1991 5.0 LX and as it had been sitting for some time, I want to run through the electrical system as a few things seem a little wonky.............like the gauges. Anyway, can you all point me to some good source for wiring diagrams and point me to the physical locations of grounds. TIA.

85GTStangGuy’s recommendation is spot on; I got one for my 87 TBird transplant and there is no way I could have done it without that guide. And get a paper copy, so much easier to use on the car.

85GTStangGuy’s recommendation is a must have! To compliment that manual I also purchased these laminated wiring diagram charts from eBay specifically for a 1991 Mustang.
