89 Or 90 Maf Harness Diagram

PM me your email address and I will send you a complete Ford Factory 89 Mustang electrical diagram set. The zip file is 2.5 MB and is too big to fit through Stangnet's email gateway.
The plug shapes on the diagrams match the plug shapes on the actual plug. The diagram is divided up by the layout of the car. The first diagram is for the very front of the car, and it works its way to the rear of the car.

Thanks. I'm ordering one but finally traced my issue to a bad fuel pump. About 5 years ago I bought a fuel tank and pump kit from LMR. I installed it and everything worked but other problems caused my car to sit for that time. I noticed a gas fume smell in the rear and when I crawled underneath I noticed the tank had a ton of corrosion and some small rust holes around the seam. I'm thinking moisture got in and killed the pump. My damn OEM tank didn't have any rust holes after 30+ years and this damn tank looks rotted. I have a new ACP tank which they say comes coated with corrosion protection but I'm thinking about buying a can of Por15 and painting the outside just incase.
