Glow plugs stay on

[dieselherb1]

I'm installing a Quantum TD engine into a caddy. the glow plug stay engaged even after engine is running and warm. Replaced relay with one from a another caddy(glow plugs come on then go off after engine warm) Is there another control? Still have a lot of wiring to hook up maybe part of the problem.

Don't know the wiring for your app., but maybe there's a coolant temp sensor that should be in the circuit?
