In an effort to help the problem I'm having with my starting problem (cranks for about 10 seconds before starting) I was advised to hook up the intake manifold heater. The wiring for this was completely removed by the PO. I ordered the relay and know it needs to be hooked to power, the manifold heater, the temperature switch on the manifold, and the oil pressure sender. My understanding is that it is made to send power to the heater only when there is oil pressure and will turn it off when the temperature sensor for the manifold passes a certain level. Other places I've read that the power should be coming from the same source as my electric choke power line. Clearly my understanding may be flawed as there are 5 connections on the relay. Here's the diagram and the connections (which were kindly installed upside-down in the case to make it extra confusing for me).
The other question I had was how long does it take for the manifold heater to work? I'm all for trying anything here that will help improve the health of my jeep it just seems like the heater wouldn't get warm enough within 10 seconds to make a difference. Please tell me I'm wrong and this will automagically fix my issue.
