were did i go wrong on the gpr bypass?

so i m doing this mod now,were you wire in a temp switch to monitor the coolant temp,once it gets so warm it wont let the gpr turn on,so when the truck is warmed up,the glow plugs will not come on.it also wsorks with the starter,were when you crank the starter it cuts the signal from gp's when they are on to make cranking easier and take some load off the batts,so intercepted the small wire on the gpr and connected it to the switch,ran other wire from switch to the relay prong #30.then ran a wire from that terminal on the gpr to the relay terminal #85.also ran wire from starter selonoid to power the relay itself,also grounded it.its not workin.the instructions arent the best but im tryin to figure them out here.can someone tell me were i went wrong? if you can foloow it?

You probably have your wiring to the relay a little messed up. Here is the typical 12v relay wiring (SPDT).

Terminals 86 and 85 are your "trigger" terminals. One terminal (usually 85) gets run to ground and 86 gets wired to the switched 12v.

Terminal 30 is normally connected to terminal 87a, when the relay gets energized terminal 30 is connected to terminal 87.

Try this:

You have the power to the GPR going through the temp switch now. You have the output from the temp switch connected to terminal 30 on the relay.
Connect the wire from the GPR to terminal 87a (you currently have it on 85)
Make sure you have a grounded wire connected to terminal 85. Connect the 12v from the starter selonoid to terminal 86.

even if you do just crank it they stay on while its running,this will eliminate them altogether when its warm,also it cuts the power to them while you are cranking the engine,therefore lees strain on batts.

Not sure exactly what kit you have but if you need to do this I would wire it like this.
On terminal 86 will be all of the triggers you would use when you do not want the glow plugs to work like factory. Like a signal from a temp switch, starter, or toggle. When any of these are activated the power from pin 30 would go to 87 which is not used.
Wire a good ground to terminal 85
Wire that used to go to GPR put on terminal 30
Wire to GPR put on terminal 87a
If the relay is not activated the power will come in on pin 30 and follow right to the GPR in 87a like it was designed from the factory.
This will allow the glow plugs to work as factory if you do not want to change anything.
Now that I wrote all that out I almost have myself confused. Sorry if this is not clear. JJ

That's what I said Only difference is he's telling you run the temp switch to the same terminal on the relay as the starter selenoid. That won't work because it will also trigger the starter selenoid when the temp switch kicks on. I would still put the temp switch in between the GPR wire coming from the ECU going to terminal 30 on the relay. Try it, it'll work.
