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?

Care to point me to a retailer? Have a PN? Autozone have them? After I get the right plug, where do I wire it from there? I'm still running the M6 harness.

Yeah I bought a Mad Dog. I ran into some problems with his tailshaft. I told them my app and they sent the old style tailshaft housing with the mechanical speedo. I called them and told them what was up and they refunded me like $20 or something. So that's no biggie I guess. I didn't like his shift/reprogramming kit so I had a Trans Go installed. My guy that installed the shift kit said that he found metal in the pan and suggested we take it out and look it over. He found that a bearing had seized on the 5 pinion planetary set so he replaced that. He said everything else looked good and the parts seemed to be what Lou claimed them to be. My guy just charged $300 to remove and replace the transmission, fix the planets, and install the shift kit. It would have cost me that much to have shipped the thing back to FL to get fixed minus installing the TG sk. When automatic shifting, this thing shifts extremely early. Not sure why since it's mechanical. Maybe I just need to adjust the TV cable. That's why I will be manual shifting it at the track. If I could go back and do it again, I probably would have had my local builder build one up with a TCI rmvb. Just my hindsight.

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.
