Stock JK TechBulletin board forum regarding issues with OE (original equipment) components of the Jeep JK Wrangler (Rubicon, Sahara, Unlimited and X) such as factory suspension parts, engine, transmission, body parts, interior fixtures and the on-board computer.
I have the MOPAR service manual for the JK and found it's missing some information, namely the locations of some of the engine bay grounding points. I thought I'd post this with all the locations identified for easy reference:
G100
G101 and G104 - These can be found under the heat shield near the catalytic converter on the right side (passenger for US folks) of the motor
G102 - This one is missing from the service manual. It's located just to the left of the right side (passenger) headlamp assembly, near the power steering reservoir:
G103 and G105 - Right (passenger) side of the engine bay
Hope this helps!
where does the ground on the passenger side block go to up top? Its dangling for me but still hooked to the block.
@availtech , thank you for posting those ground locations. Is yours a 3.8 liter? I've got a 2013 JK with a 3.6. I was able to find G100, G102, G103, and G105 using your diagrams and photos. However, on my Rubicon, I did not find G101/104 together under the heat shield. Instead, I had to pull the passenger side wheel well cover and then a single ground is on the block. Additionally, I have an additional engine compartment ground on the driver's side by the washer reservoir. Photos below. Block ground, passenger side, remove liner. Ground, driver's side, behind washer reservoir
Just uploaded in the hopes it helps someone track down an erratic electrical problem.
The G104 is the first photo doesis that ground for o2 sensor. I have o2 sensor heater short. I can't find anything on the ground wire location for 2013 jeep wrangler 3.6
