Need to wire up an electric fan on my 360...
Sounds like you don't have "all this stuff."
You need to buy a good heavy inline fuse holder, preferably with no 12 or 10 gauge wire
If you have the Mopar starter relay, the battery stud on the Mopar relay makes a good place to take off from. The Mopar relay looks like this:
You cannot use your Mopar temp sender which is for a gauge. You need a temp sender SWITCH designed for a fan. These come in several designs, some screw into the intake manifold just like your gauge sender, some have a sensor tube that clamps onto the bottom of the top hose, and some are adjustable
The relay they are referring to is known as a "Bosch relay" and is a common, standard, general purpose auto relay. Most parts stores have 'em, and you can buy a connector that fits the bottom
If you look at the bottom of a Bosch relay, the terminals are numbered: Some have 4, some have 5 terminals
Just wire it like the destructions describe. The control coil of a Bosh relay is terminals 85 and 86. These do the same job as the two "push on" terminals of a Mopar start relay. That's the magnetic coil
The "normally open" contacts of a Bosch are terminals 30 and 87. These are the "switch"
So wire terminal 85 to the same place as your ignition power on/ off. This will power the relay, and when the fan thermostat ---which will connect to 86 turns on, the stat switch will ground term. 86, turning on the relay
The main power running the fan, the "switch" part of the relay, will be a big fuse coming from the battery (starter relay stud) to terminal 30. So this is hot all the time.
Then term. 87 goes off to the fan
