No glow plugs on a 150, no 7.3 in a 150 either.

I don't know ford diesels as well as others, though I am learning with my 6.9, but
I would say the relay is intergrated into the computer. Spend the $100-$200 and get the controler.

I can tell you how to install a manual switch if you want.....I am going to take a picture of mine first though.

There is no computer on a 91 unless you have your laptop with you.

This diagram should do the trick for bypassing the timer
