  1. Fuel Pump Harness (where does it break out)?

    YJ Tech Forum
    I've just installed my new fuel pump but I can't find anything coming out of the harness than runs to the rear lights... Is that the harness that usually carries the fuel pump wiring back? It's a '94 YJ pretty well stripped by the PO so a lot of stuff is missing but I don't want to buy if the...
  2. Gauge cluster fuse(#9, 15 amp) keeps popping

    YJ Tech Forum
    New to the forum so correct me if I'm posting in the wrong neighborhood. Now to the problem. So I just picked up a 1993 YJ 2.5L 5 speed and drove it for a few days without issue. Then all of a sudden all my gauges stopped working at the same time. The lights all still worked(except my brake...
  3. Wire aux lights to be used with or w/o high beams

    JK Tech Forum
    I'm working on installing a set of KC HiLiTES 151 Apollo Pro 6" 100 watts. I'd light to install so I can use by flipping on high beams and/or have high beams on w/o the auxiliary lights. I've got a 2017 JKU with the manual tranny (important info for wiring through firewall) and very little...
  4. Can anyone name this wire?

    JK Tech Forum
    I have Lumen LED headlights with switchback halos. My ex who installed the lights a few years ago used electrical tape when he installed them resulting in a wire being so bent that it broke off and now the amber led in the halo does not work. Can anyone name this wire other than "switchback halo...
  5. 4 Pin Trailer Wiring

    JL Wrangler Technical Discussion
    I notice all the wiring kits require a hot wire ran to the battery. What is the reason for this, does anyone know? My jeep has traditional halogen tail lights and my trailer has LED's. Not sure why the wiring would need the extra power from the battery.

  8. Brake Lights stick ON

    YJ Tech Forum
    Put a new brake booster on my 1992 YJ this weekend. Simultaneously, a friend who swore he knew what he was doing (he didn't) attempted to wire an in-dash horn button since the one in the steering wheel has been dead for some time. (He didn't ... my horn is still dead but that is another issue...
  9. ARB not engaging or disengaging correctly

    TJ Tech Forum
    The ARB in my front axle is not engaging or disengaging correctly. When I hit the switch for the compressor and it pressurizes the line the locker will engage right away, no waiting for the switch to be pressed. If I bleed the air out by cracking the line open the locker will disengage...
  10. Parking lamp holder connector "designation"?

    JK Tech Forum
    For the connector from the wiring harness to the parking lamp holder is there some kind of designation/connector type? I'm talking about the holder itself, NOT the bulb type. I'd like to build a harness extension with a built in load resistor and pigtail for switchback wiring without cutting...
  11. One for the wiring experts: On/Off DRL?

    JK Tech Forum
    Hey guys, Quick question for any one of you more familiar with the fuse box than I am; How would I go about wiring my DRL (2017 RHD Wrangler jk) to either: a) Turn on with the low beams (And any higher beam pattern) OR (and ideally) b) Turn on when the first setting on the headlight...

    My turn signals aren't working. 2003 Sport with a 4.0L Bulbs, relay, and switch are all new. When I press the brake pedal the signal will light steady. Only the rear ones though. Winner gets a free shirt.
  13. JK Mysterious connector behind steering wheel/radio

    JK General Discussion Forum
    I am upgrading the stereo in my 2014 JK Sahara soft top and discovered this connection. Nothing was plugged into it. Is it for upgrades? I don't think it is for hard top. Oh, and I have the alpine equipment. (which I am totally bypassing with new stereo/amp/sub install). Just curious...

  16. What is this 3 prong plug in the grill? 2013 JK Unlimited Sahara

    JK General Discussion Forum
    I bought a used 2013 Wrangler Unlimited Sahara and there is a 3 prong plug (that looks like it is wired directly into the battery?) located in the front grill. My old 2009 X Sport definitely did not have this! Does anyone know what this plug is for?
