Brothers Tach Dash Conversion Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Mryan** · 06-01-2019, 03:52 PM

Brothers Trucks sells a conversion kit to install a tach into an existing dash, can anyone tell me if this kit will work with an HEI distributor?

Yep, it sure will. I bought the 5k rpm tach conversion kit, Brothers part #TACH772. Works great.

Did you use Brothers wiring harness? How did you wire brown wire to distributor? HEI
Thanks

I installed the. 8K version (didn't have a 5K kit in stock at the time) Has worked with 3 different HEI distributors so far. I already had a wire coming in thru the firewall from the tach so I just connected the brown wire to it.

I added a factory tach from a big truck gauge cluster. I used female spade lug connectors on the tach and ran my own wires to the HEI and power.
