What amperage does the TCC Solenoid draw? Want to wire a MS3X to control the 700R, and need to confirm if a relay is required (or not)..

The stock ECM does not use a relay to drive the TCC solenoid, so I doubt that one is needed. It does use a quad driver, so take that into consideration.

This link says the quad driver is rated at 1 amp per channel, so it's not a super heavy duty part:

That 1amp value is what I needed to know. Anything over 3 amps requires a relay for the MS3.

Thanks.
