Instead of using the red ACC wire, try the yellow constant wire.

After a while i gave up on it just decided to use a radio shack toggle since it was rather simple to solder. Drilled a hole in the pocket compartment of my dashkit and just installed the switch onto there.

Thanks for your great help gnat im pretty sure someone else will find all the info useful ha

Sorry it didn't work out for you, the 5000 might be more critical on timing than my 6800DVD. You could always try one of those eBay solutions.

its totally fine, but i think if somehow the solution was tweak a bit for the 5000 im pretty sure it would work fine. Guess someone else will have to try it lol

Pics of my bypass doohickey, maybe it will help somebody to actually see it? I made it out of spare parts desoldered from old circuit boards I've collected over the years, even the wire was used. Heatshrink insulates the pins and a larger heatshrink holds it all firmly together, the wire tie prevents strain on the components.
