Faulty wiring can have its fair share of headaches, which is why CJ Classics engineered the USA Made Underdash Wiring Harness with the correct color-coded wires and color-molded connectors to ease the struggle. Made specifically for 1965 Mustangs with Gauges and a 3-Speed Heater, the installation comes down to a simple and high-quality replacement with pre-assembled length to eliminate cutting, splicing or crimping.

Features and Benefits:
- Connects to OEM Switches and Gauges
- Pre-Assembled to Length with Color Molded Connectors
- Correct Color Coded Wires
- Powers Instrument Panel Cluster, Console Feed and Door Courtesy Harnesses
- High-Quality Replacement

*Requires a 3-Speed Heater Motor.

The power supply from your 3-speed heater motor's new Underdash Wiring Harness will also power your instrument panel cluster harness, console feed harness, door courtesy harness and wiper motor. Full replacement assemblies mean factory-style components, such as fuse blocks, lamp sockets and OE-correct wires and connectors. Feed the wiring harness through the firewall behind the instrument cluster and wire your factory, OE-correct components to their original position.

If you have gauges and a 3 speed heater motor it will work.

Asked by: Pud Mc
It would require modifications to the instrument cluster harness to work with the new vintage gauges, there is not a gauge harness for the cluster.

Does this wiring harness include the fog lights which are standard with a 65 GT? If so will the tail lights turn on with the fog lights? 

Asked by: Dearborn GT
No, this isn't what you want for fog lights. Look up CJ part # WFGUD1. There's a full installation video on the product page, so you can see exactly how it installs.

What is the difference between a 65 gt cluster and 66 cluster? Wouldn't the 65 gt have to have deluxe int. to have gauges? I have a 65 gt with deluxe, but orig cluster is gone. Which would be correct for my car? Build date is April 21. Thanks.

Asked by: vintagemetal66
All 1965 Mustang GTs had a unique amp gauge that was different than both the regular 1965 Mustangs and the 1966 model. That's why the wiring is different. If your car was a 1965 GT, you'll want this wiring harness and the proper 1965 GT gauges. If you have a standard 1965 Mustang, you won't have gauges at all - just "idiot" lights. The standard vs. deluxe interior issue isn't an issue at all, as a 1965 GT could have either, but would still have the same GT gauges.
