Your cart is empty.This inexpensive protection for an electric fan and a vehicle's wire harness. Provides constant voltage, protects from voltage and amperage spikes and prevents the fan from back feeding voltage through the vehicle's wire harness. An absolute necessity if adding a dash mounted manual on/off switch to your electric fan circuit. This kit includes: SPST 40-amp relay, 30-amp circuit breaker, relay base with harness (6' input, 4' output), crimp-on terminals and mounting hardware.

Very good product. My only complains is the circuit breaker mount ears are too close to the breaker. You cannot install the provided hardware straight on with normal tools you would expect someone to own. Your bit cannot fit in that small of a space.

Good quality. I always buy painless when doing wiring. Comes with everything you need if your wiring to ignition power and want the fan to run every time the key is in the on position.

I installed a painless wiring harness in my 67 c10 and this is a must if you are running electric fans. Plus since it is the same brand, they work great together.

This product is missing most of the stuff thats in the description. No relay. No ends . Just the relay block and wires.

This is a relay kit. It is supposed to eliminate the need for buying a ton of parts to install you electric fan. WRONG. 1: It DOES include a relay. YAY! 2: There is plenty of wire on-hand to wire the fan itself, if you wish to mount the relay on your CORE SUPPORT. If you wish to mount the relay next to your fuel pump relay or other relays on the firewall for a factory appearance, your left adding length to the wires. You WILL need black wire (10 gauge) for the negative side of you fan. This kit comes with NONE. 3: Since you are forced to mount to the core support (unless you want to add wire), a problem arises in that the grey wire is not long enough to reach the passenger compartment (so you can wire to 12v acc/switched at fuse panel). 4: The black wire is only 2 inches long. You will need to add wire (14 gauge) to attach to your thermostatic switch on your intake. 5: The 30A breaker is useless. Buy a 30A inline fuse. So, this kit is ALOT of trouble for what it costs. I suggest (since you are going to be buying wire, a fuse, etc) going to a salvage yard and cutting a relay off of a donor car. While you are there, steal all the convoluted tubing you can. Then stop by your favorite parts store and buy the necessary wires, terminals, etc. You WILL save money this way and get the relay setup that looks factory, and not cobbled together while still spending under $100.
