Ok, so I've used the search function for 2 days now and I just want to make sure I'm doing this right. Well, at this point I want to make sure I buy all the right stuff and don't have to make a half a dozen trips to the store, but then I will want to do it right. I also don't want it to look all crappy and messy when I'm finished. Once I get all the stuff I need, and the proper instructions, I intend to do a pictorial write up about this for everyone's benefit.
Here's what I have/know I need....
Fuel shutoff solenoid off of an class 5 or 6 truck (thank you TSTC).... This is the slightly bigger one. I have the bracket that fits it. The solenoid has the wiring harness connector still attached.
I have been reading all about this and I know I need a 70 amp 3-prong relay and some of those lil blade terminal thingys to slip on the relay prongs.
I know I need an inline fusible link in 65 amps.
And I know I need a bunch of wire.
This is where I get all cross-eyed and confused. Let me just say that wiring in general confuses the hell out of me. In theory it should be simple, but I just can't wrap my brain around it and then I start second guessing myself.
So, the solenoid I have has 3 wires, red, black, and white. They all appear to be the same gauge wire. If what I've learned is correct, black is ground, white goes to the relay and red goes to a key on "hot" wire. I know at least one person grounded the black wire to the cylinder head, is there any reason why this is a bad idea? I saw where someone else spliced the red wire to the fuel heater circuit. Does that circuit have enough power to hold the solenoid open? Someone posted a wiring schematic from Dodge and it shows that the fuel heater circuit is 20 ga wire. The wire coming from the solenoid is much larger than that, which gauge wire should I use to route the red wire?
Now on to the relay wiring.... Does it HAVE to be 70 amp? This would be more helpful if I already had the relay and I'm sorry for not thinking of it before I began this post. How do I know which prong on the relay does what? I know there are numbers on the bottom next to the prongs, but the only relays I've messed with are 5 prong, so that's the only notes I have to look at. The wiring diagram posted by someone shows 14 ga wire going from the relay to the battery, 10 ga wire coming from the solenoid to the relay and 12 ga wire going to the (insert useless components here and replace with starter solenoid). Should I use that gauge of wires?
Ok, last couple questions. What's the difference between an inline fuse and a fusible link? Does it HAVE to be 65 amp? And finally, where the heck in this wiring mess does the fusible link go?
