Just wanted to let you guys what I found. One of My intake heater grid relays was fried and my truck was running rough and smoking on cold start. I looked back on a few threads and found someone used Ford starter solenoids to replace them. Well so far it is working for me, went down to my local napa and got 2 starter relays for 10 bucks a piece and mounted them in place of the old assembly and whala!! another cheap fix.
