2013 grade, work truck package drive monitor install but without the accessory meter LCD in front display...
bought the drive monitor switch to replace my blank button panel, plugged it in and it didn't work. Before I get started with the jl1/j28 jumper wiring my front display does not contain the accessory meter LCD for displaying the MPG / drive monitor functions. (Deleted in the work truck package) So I purchased the OEM toyota accessory meter which contains the drive monitor LCD readout and have installed it. What happens now is when I put the key in and turn to acc position the clock display's but after ignition the screen goes black and on the successive try the display no longer shows the clock. I can disconnect and reconnect the battery negative and repeat this same pattern where the clock display's until you turn to ignition. Are there wiring instructions for switching the front display with only the clock to the front display that includes the drive monitor LCD?
I do have the wiring harness behind the blank switch plate, its just not working (plug and play) style...

Installed Drive Monitor Switch (had 8 wires)
Replaced the Accessory meter (mpg/temp circuitry was not in this one)
Added 3 wires from Junction JL1(pins 17/19/20) to Combo meter J28(pins 28/29/30)
Added 1 wire from Combo meter J28(pin 31) to Accessory Meter K20(pin 10)
Added 1 wire to Accessory Meter K20(pin 23) to IGNITION POWER "KEY ON" (without this, the accessory meter (mpg display will not light up, only the clock will come on).
