multi- flex silverado

[Trailboss want to be]

Does anyone tried switching out to a multi-flex /and if so how to wire the second switch to release the middle section. The harness has an extra solid purple and solid yellow wire which didn't exists on original harness. Any thought or ideas would be great., wire diagram of harness would be helpful.

No one has been able to make the inner gate work electrically. The main gate will work as normal. I read someone had rigged up some zip ties or something to pull the inner latches to get it to open. There isn't support from GM to add the programming to make it work, even if the electrical wiring and BCM would support it.

I'm going to run a separate connection to the other switch to bypass the bcm ,don't bother me it someone can open when in park, it will be like the old school chevy before the computer days, shouldn't be that hard.
