Stage 2 “Tucked” Mil-Spec Engine Harness (95-99 2G DSM)

(1 customer review)


This stage 2 engine harness utilizes a firewall boot and a metal plate for installation as-well, but utilizes Raychem DR-25 for protection which protects the harness from any solvents.



This Mil-Spec OHM Racing Plug & Play Wire Harness was designed with a “tuck” in mind.

Firewall plate and firewall boot included, this stage 2 harness does not have a master quick disconnect circular connector, if you are looking for that please check our Stage 3 harness.

OHM Racing Plug & Play Wire Harness offers Mil-Spec Teflon wire ranging from 16AWG to 22AWG and brand new pins seals and connectors. The Teflon coated wire is loomed with Raychem DR-25 heat shrink protection, firewall boot, and Raychem ES-4 adhesive lined junctions. Each brand new connector is crimped with pneumatic heads to ensure an OEM crimp, and labeled with a label. All heavy interference circuits are protected and grounded properly and no soldering is used at all on this harness (soldering can crack on vibration) only KET open barrel splicing everywhere its needed covered with adhesive heat-shrink as well. we even took the time to label every single wire for you.

The harness is 100% quality tested pin to pin, and Hi-pot tested before shipment.

    Bought this harness, took a little over 4 weeks to get to my door. It was well worth the money and the time. The work on these is amazing. It was put together so well, labeled. Company is amazing, always replied to my emails. Even emailed and asked me how the install went. If you want the real deal for your 2g. Look no farther. It doesn’t get any better then this. ?
