The picture at view is the actual harness we build in house, from scratch. Note : options that you add may change the physical look, but the form stays the same what you see is what you get.

The benefits of a fly by wire system are. You won’t have to worry about hanging a pedal or ordering a special cable / bracket. Just let us know the requirements that your environment creates and we will build you a solid LS7 fuel management harness.
