It finally happened. The TIPM said NO to starting with the key. It will start fine when it doesn't throw a tantrum but it's been just throwing a fit and cuts power before the starter turns. So my question is, am i good to just hook up the small solenoid wire at the starter to an auxilary switch or do i need to do more work than this?

 

According to the wiring diagrams I have access to, all you really need to do is supply 12 volts to the yellow/grey wire, connector C9, cavity 2.

 

Should I cut the wire from the TIPM and cap it off or is it fine to just have the auxiliary switch on a T splice/Positap. Don't know how these computers will handle seeing voltage when it doesn't expect any.

 

I don't know if the PCM even cares...... The TIPM is just 'mystery electronics', I don't have wiring diagrams of the inner workings of said electronics......

In any event, you can likely tap the wire anywhere, and not worry about disconnecting it from the TIPM..... though doing so certainly wouldn't hurt.

 

That it is, a mysterious box of unreliability and failures. Anyway i'll go do that thank you. Do you know of a good place for diagrams by the way? I have the 2006 repair manual but it doesn't have everything as thats before they combined the two modules and sadly the ram body builder diagrams vanished once explorer compatability mode for edge was removed sadly.
