Retrofit 700r4 lockup question
With gas as high as it is, I thought I might wanna install a lockup switch in the car. The TC is lockup type and the GM solenoid is in place, but of course I didn't use the A4 harness so I don't have lockup. I do have an A4 flash image in the computer. Without buying an A4 harness, can one get the lockup connector for the trans and wire it into the appropriate pin for the PCM? If so, can someone tell me how to wire it in or point me to a schematic? I am assuming with the A4 flash image, I can get the computer to control the locking and unlocking of the convertor. Can someone confirm this? Will the brake switch unlock it? Thanks in advance.

Just to clarify, I just want to control lockup only. I do not care if it knows which gear I am in or anything like that. It's starting to look like the connector on mine might differ from that of the 4l60e....... Does this complicate my situation or no?

IC, I think I may be going with the B&M lockup control. It's a little pricey but it can control lockup based on speed. So all I have to do is determine about the MPH where it shifts into overdrive, turn my ****, and I have lockup.
