TCC ?

[ak diesel driver]

where's the best place to tie in a switch to manually lock the TCC on a 93?

I tied in by the ECM plug. Switch is on the aftermarket radio insert. Keeps the splice dry.

Be advised the stock TCC won't hold well below 45 MPH, compresion braking will slip the overrun clutch in manual 3 rd.

Remember which wire?

I'm not 100% But I think I remember it was a brown wire, I know that don't help that much,, memory , she ain't what she used to be.
