I sent my harness off and got it simplified and it came back with no park neutral safety switch plugs on it, he said they are not used. I am putting it in my 1985 silverado. I thought that the ecu needs to know what gear the 4l80e is in.
LQ4/4l80e PARK NEUTRAL ?

Nope, the PCM tells it exactly which gear to go into. The other switch is for the dash and not necessary in your 85.

I don't have a safety switch on my '81 and it works great.

Don't start it in gear though.
The older trucks have the shifter/starter interlock in the column but you probably already knew that.
