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?
