Alternator Lead Wire Repair Harness Connector Replaces CS130 CS121 CS144 Fits 1986-1996 GM

Had an issue with intermittent charge failure. Diagnosed it to a bad alternator and faulty charge harness. Wires are a little bit loose in the body of the connector, that is the only reason for 4 stars. Otherwise this is the correct part for the application. Don't forget to put a little dielectric grease on the connector before you install to help prevent corrosion damage.

I am in the process of rewiring a 1967 Chevy Nova that has a custom crate engine being installed. Luckily I could find this connector, as the custom wiring harness is made for the older style 2-position connector for the alternator. You can easly Google search the functions of each of the 4 wires. I removed 2 of the 4 wires, as there is no ECU connection, and I believe the other is for a revolution monitor.

I used this to convert a wiring harness to the new style alternator. Good quality, no issues. There are no instructions or wiring diagrams, so you'll have to find them online. This is not an issue if you are doing a exact replacement to an existing 4-wire harness.

Upgraded my 1996 C1500 to a 140 AMP alternator. this was a perfect fit and fix.

Came super fast, revived right on time! Same as OEM plug, fit perfect works great!

Was as expected to wire in a 140A CS144 alternator for a project on a Toyota 3.4 swap, excellent product!

Did the job
