Hi all,

I decided to upgrade the headlight harness in my 2001 Jeep Cherokee Sport.

For the most part, these are the directions I followed: http://jeep-xj.info/HowtoHeadlightLoom.htm

My issue is the headlights are on, even when the switch inside isn't pulled to the on position. When I pull the switch out to where the headlights would normally turn on with the factory harness, they shut off with the new harness.

The following describes the connections I have made:
-Red fused wires connected to the positive battery terminal
-Black headlight ground wires connected to the negative battery terminal
-Relay ground wires connected to a radiator support bolt
-High- and low-beam jumper wires connected to the factor headlight socket on the left side of the vehicle (as viewed from the front)

This is the type of relay I bought:
Any ideas on where I messed up?

Thanks,

Bronson

 

If you look at the schematic for the two relays, you will see they aren't the same.

Yours has a normally on and a normally off contact while the one in the article has two normally off contacts.

I suspect you have connected to pin 87 and need to move that connection to 87a.

 

That makes sense! Since I'm only using 2 relays and not 4, I'll snag some of the correct kind and let you know how it goes.

Thank you very much,

Bronson

 

It worked like a charm! Used NAPA part number AR274.

Thanks again for the help,

Bronson

 

The ones you had should have worked fine. You just needed to change the connection from 87 to 87a.

 

I already had the wiring set up to use all 5 pins on the relay. Yes, I could have just used it like a 4 pin relay by crimping two wires into a female spade and putting it on one of the 87 pins, but going the route I did made it more of an adventure

Your suggestion would have saved me some money, though. The original relays I purchased were about $3.50 each. The NAPA AR274 relays cost nearly $20 each. If anyone else finds themselves in the same situation I did but you're strapped for cash, use sreeb's method.

Cheers,

Bronson
