TJ Hand Throttle Installation

Have you ever been caught between a rock and hillside and you need an extra foot? Well, a hand throttle may be the thing for you. If you have a manual transmission and sometimes you need an extra foot to get over the rocks or keep from rolling backwards on a hillside then this is the “BOMB”.

There are several write-ups on the net and this is the one that works for me. Most everything I got to do this was given to me or was really cheap to buy. Cost me a breakfast at Mickey D’s for one item. Thanks TJODD!

Here is a list of materials:

1. Gear shifter from a 10 speeds or equivalent bike. Make sure you get one without detents cost 1 breakfast at Mickey D’s



2. Spare heater hose ½” or whatever fits gear shifter. Cost FREE had extra hose in tool box



3. Bicycle cable kit from Wal-Mart. 2 cable worked and 2 were extra that I didn’t need. Cost $12.99 or so give or take a few bucks.



4. Adjusting hardware from bike shop. They let me look through their nut and bolt bins to see what I could use. Found a long slotted threaded adjuster with a thumbscrew. Cost FREE



5. Throttle return spring from Jeep dealership Cost $5-$10 dollars.

First Step: I located throttle on shifter where it wouldn’t interfere in shifting. Use heater hose cut to size to help clamp to gearshift.

Second Step: Run cable through grommet through firewall, I previously ran some fog light wiring and had a hole there. Seal with silicone.

Third Step: Route cable to throttle body, be sure to keep off anything HOT. If you have cruise control you will have to fabricate an “L” bracket and attach to throttle cable bracket. I mounted mine where the auto tranny shifter cable goes. Using the adjusting hardware and washers I threaded my cable and wire through and secured it to the throttle bracket with washers and nuts.

Fourth Step: On the new throttle return spring, bend the spring to remove the gray clip, thread the wire from the cable through this clip. Attach to the throttle allow a little slack and install cable crimp connector.

Fifth Step: Adjust tension on hand throttle so it will return to idle when released.

It takes some getting use too, but it is sweet when you need it. I have used it a few times and it works great. My first time out I had the cable to tight and it kept my throttle above idle so I had to re-adjust the cable so it would return to idle when released.
