The below circuit has not been tried, for information only, use at your own risk.
It is the missing image in my post in the above thread.
From another Poster after buying one in the above thread:
"The resistor that goes across the EVR connector is 75 ohms plus or minus 5%. The wattage is probably 10 watt minimum. Its a wire wound reisitor and is big around as a pencil. It may even be 15 or 20 watt resistor as wire wound resistors are higher wattage in a smaller size.
The three pin plug that goes on the EVP harness is siliconed up and I can't see what is in there across the pins. I'm not having any luck with my ohm meter across these pins so you will have to give me more time or wait until you get one.
OK, I couldn't stand it... I took the plug out of the EVP three pin "fooler" and there are two small resistors in there with a third component that is covered so you can't see what it is. For all I know it may be a bare shorting wire covered up. Sorry, I can't be of more help....
The kit comes with a resistor and votage divider connector
The reading across the connector are as follows;
352-359: 371.1 ohms
352-351: 2.04k ohms
The stock plunger
(extended)
352-359: 37.4 ohms
352-351: 3.47k ohms
(compressed)
352-359: 3.44k ohms
352-351: 290 ohms"
