Re: Why don't I have a anti dieseling relay or switch?

I believe those relays were discontinued in 1971 which would explain why your truck doesnt have one. Does your truck shut off when you turn the key off? If so they you dont need it. All it does is engage the AC compressor for a few seconds after turning the key off, thus putting load on the engine to kill it. Sounds like a bandaid for a bigger problem.
