Question:
Being that C and E both come from the same source. Can I run a jumper from E which does have power to C which does not have power. Without doing damage to ..........
I checked B it is grounded.

Thank you

Id trace down why its not there in place of doing a jumper across. Less likely to come back to bite you later.

I got up bright and early on Saturday. And installed a wire from E to C drove the car and the OD did NOT come on. So then I went under the car and squeezed the connector and drove the car and the OD DID come on. So I undid all that I did. Went to Radio Shack bought the correct size connector about 5 bucks for a pack of ten. Put it on the wire and the OD WORKS !!!!!
And as far as not needing gas millage out of a Corvette. The car was getting about 16 mpg at 65/70 mph now it is getting 20 mpg at 70/75 mpg. Thank you all for your help. Take care

Overdrive makes all the difference in mpg and range. Congratz on getting it fixed.
