TFI relocating kit

 

I relocated mine on the airbox. 88 e-150 302

 

Nice
No heat sink?

 

Oh, yeah. Here's the other side. I ordered some generic heatsink material from Amazon but any old dead computer power supply heat sink will do. The location in the intake airstream while the engine is running guarantees the most airflow possible. Of course, just moving it off the intake is a huge plus.

I had a 92 F-150 with remote mount on the driver's fenderwell and I moved it also but it already had the newer harness. jim

 

Sweet!
Too bad the Ford company didn't take care of this issue!
Thanks for all your help and info

 

Glad to do it! Just passing along some of what I learned here, that's what makes it work out.

BTW, there was a class action suit against Ford for the distributor mounted TFI. THAT is what drove the move to the fender. It was the very early days of EFI/EEC, etc. jim
