Caterpillar Combo Harness

Caterpillar Adjustable power set, add HP and MPG
This harness will give you more power off the line and pulling at highway speeds. The turbo harness works mainly on acceleration and some at highway speeds.
Use it on 3406E, C15, and C16 engines also C-12. Will Work on 1993 and newer engines.

These are quality made, using new factory parts. All connections are soldered and sealed with heat shrink tubing. They are weather tight.

You will get the Boost cable and the Fuel temp cable. 
The turbo boost cable has a 10 foot lead and adjustable control. You run this inside the cab and mount on the dash. This is adjustable with a 10 position dial. Very simple to install.

Any questions please email me.
There are two different style harnesses. You will need to let me know your engine serial # prefix on order and I will get you the correct cables. MXS engines I need complete serial number.
