This harness uses Mil-Spec Teflon coated wire with a maximum heat rating of 200°C . The Teflon coated wire is loomed with The highest quality Raychem DR-25 heat shrink covering, and adhesive lined wire junctions to keep moisture out. Standard wall ethylene-tetrafluoroehtylene (ETFE) insulation ( also known as Tefzel ) designed for aerospace applications where weight, dimensional tolerance, and mechanical durability are required. This wire exhibits high chemical and radiation resistance.
Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a yellow identification labels for easy installation. All heavy interference circuits are protected and grounded with proper wire covering.
All connectors and materials are new. Each connector is crimped with pneumatic heads to ensure an OEM crimp every time, then tagged with a white identification label for easy installation. All heavy interference circuits are protected and grounded with proper wire covering. Our engine harnesses are 100% quality tested pin to pin; And resistance checked to ensure no voltage fluctuations.
All Rywire engine harnesses are made with OBD1 (92-95) ECU Connectors. An ECU adapter can be used for OBD2 ECU's if necessary however our harness does not support USDM OBD2 ECU's. Aftermarket ECU's using OBD2 plugs and Non-US OBD2 ECU's are compatible (except for H22 and GSR stock computers).
Each harness will come with a custom back side sub-harness that will be proprietary to the chassis you choose on the drop down menu. This way if you ever change chassis you will only need a new sub-harness, not a whole new wire loom!
Because the back-side (interior/shock tower connection) separates from the main harness, the engine harness can be used on multiple chassis provided the engine itself uses the same components.

Wire length between the two connectors is short for a full-size pickup
Size: 16AWG Wiring Harness-2 Leads
I used the harness to wire ditch lights on opposite sides of a full-size pickup (F150). The wire between the 2 2-pin connectors was about 18 inches too short. Fortunately, splicing the wires from the (Nilight) ditch lights and the included pigtails gave barely enough length to reach the connectors. The connectors are buried inside the trim channel for the cowl; I'd have preferred they were exposed on each side to allow for easy swapping of the lights, but I can live with it. There is more than enough wire from the first connector to the relay for my all-under-hood installation, but I didn't think to measure if it would reach into the truck bed. The harness is of good quality and is a very good value. It would be a 5-star if it weren't for that little length issue.

great value
Size: 16AWG Wiring Harness-2 Leads
very affordable light install kit. worth the price just in the wiring connectors. I used this with my Nilight front bumper kit. i bypassed the button and wired high beam (+) to the yellow small wire. I did this so when the highbeams come on the light bar comes on. because with the stock arragement of this harness, the button continously draws power for the indicator LED
