Renix Engine Monitor AW-4 Auto Trans DIY Upgrade Procedure:

Parts list:
 - few inches of Jumper Wire
 - 1k ohm Resistor
 - 1x .093" Molex Pin # 02-09-2103
 - Fine tip soldering iron for alpha models

Alpha REM Upgrade (V1 Board)
 - Solder 1k ohm resistor from Arduino pin A3 to PCB left pin under REG1 (5v).
 - Solder Jumper Wire from Arduino pin A3 to PCB Ethernet Jack pin 1. (Board must be removed from case. Looking at ethernet jack side of board with screen facing up it is the far right pin closest to the buttons.)

Alpha Renix Adapter Upgrade
 - Cut a small bit of wire (1/2") and crimp it to the molex pin, make sure to solder wire to pin for best results.
 - Insert pin into Renix adapter hole 15 (looking at adapter from above with jack facing forward, it is the top most far right pin.)
 - Push the pin all the way down with needle nose pliers until it contacts table. Flip adapter over and push pin back up until the wings contact the bottom.
 - Solder the free end of the new pin on to Ethernet Jack pin 1( looking from back of adapter in, it is the far right pin on the bottom row.)

Beta REM Upgrade (V2 Board)
 - Solder 1k ohm resistor from Arduino pin A3 to PCB pin 5V rail. (Make sure lead is bent so it doesn't touch any other pins)
 - Solder Jumper Wire from Arduino pin A3 to PCB pin E1. (Near Ethernet Jack)

Beta Renix Adapter Upgrade
 - Open lid and note wire color of the pin in the center, closest to the Jack. If wire is BLUE, it is a 2016 model. If wire is GRAY, it is a 2017 model.
 - For 2016 model, pull out the free RED wire. For 2017 model, pull out the free WHITE wire.
- Strip the wire an 1/8" and crimp it to the molex pin, make sure to solder wire to pin for best results.
 - Insert pin into Renix adapter hole 15 (looking at adapter from above with jack facing forward, it is the top most far right pin.)
 - Push the pin all the way down with needle nose pliers until it contacts table. Flip adapter over and push pin back up until the wings contact the bottom.
