Assembling the Optical Sensor

for the Throttle Jockey Pro

It makes sense to stagger the solder joints so your sensor wire doesn't look pregnant. Remember to slip you piece of 1/4 tubing over the wires before you begin any soldering. My tubing was just a little too small to slide over the Futaba connector.

I start off by soldering the white sensor wire to the connector signal wire. If this were a Futaba cable it would be the white signal wire. This particular wire is orange-signal, red-current and brown for ground.	Next I connect the black wire coming from the connector cable to the blue and green leads coming out of the optical sensor. These are the middle two wires on the sensor. Don't forget the heat shrink tubing!

This is the 100 ohm resistor soldered inline. Make sure you get a good solid "wet" solder joint but don't overheat the resistor unnecessarily. The resistor is very small, it's less than 3/8" in length not counting the wiring which can be trimmed as needed.	The same solder joint with heatshrink tubing applied. Remember to slide the short piece of heat shrink tubing on one wire BEFORE soldering. Make your tubing only as ling as you need it.

Here's the finished piece. I had the 1/4" piece of heat shrink already on the wire slid down near the connector. Once all individual wire were soldered and sealed I then slid the tubing in place and shrunk it down to wrap everything. I left a little unwrapped near the sensor, this one is mounted on my Fury which has a rear facing motor so I needed the wire to make a quick 180 degree turn so I left it unwrapped to make that turn in less space. It's a little easier to get to your motor mounting bolts leaving the top a little more open as shown in my pic above. I hope this gives you a little insight on what we're trying to do here. Take your time and you should have a very reliable sensor.
