    Trick, functional jake brake grenade shifter

    I turned on the power (12V) and I took the test light to each power junction in sequence to make sure each leg of the circuit was sound before I let the voltage flow to the next point: battery ‐>relay->clutch switch->throttle switch->rotary switch->LO circuit->HI circuit. No smoke escaped and...

    Trick, functional jake brake grenade shifter

    The wye connector handles the LO setting (front & rear heads) so one wire loops back around and joins up with one of the HI wires and same with the front head. I'm really impressed how the male rubber cover worked out! Looks very clean and pretty close to what factory wiring could've looked...

    Trick, functional jake brake grenade shifter

    I finished the wiring from the firewall to the jake heads today! I made some 10 ga. standoff brackets welded to 1/4" thick spacers to hold the wiring along 4 valve cover bolts and used flange head bolts to attach. Under the first bracket is a 3/4" and 5/16" p-clamps to hold the wye connector...

    Trick, functional jake brake grenade shifter

    I completed the wiring from the clutch switch to the throttle switch and back to the dash this morning. The dimmer switch screw is doing triple duty now since I added a p-clamp to it to hold the wires. The dimmer wiring p-clamp had enough extra room to add my two new wires to its bundle. I...

    The clutch switch bracket turned out better than expected - no grinding or tweaking required at all! It fit just right. I replaced the factory high beam light switch screws with 1" long button heads which provided enough extra screw threads on the backside to attach the bracket with nylocks...

    yes, I have access to laser cutters, CNC press brakes, full machine shop, saw shop, tube benders, welders, hydraulic hose crimp machine, powder coating & wet paint shop, blasting booth...etc. Basically, everything you need to do this stuff the right way. All one needs is some imagination...

    Trick, functional jake brake grenade shifter

    The switch brackets were laser cut out of 14 ga. stainless steel and formed up to the shapes you see. The welded 1/4" nut that's been drilled out on that Z bracket will index the bracket to the throttle lever just like the original throttle lever bolt so it should always stay straight. The...

    Trick, functional jake brake grenade shifter

    I finished soldering the diodes in the wires for the HI setting last night (front & rear head wires get diodes, middle head is just a plain wire) and covered them up with wrong size heat shrink but I'll let it slide this time. This morning I attached the 5 legged spider looking harness to the...

    That terminal spray is a good idea especially for the clutch switch which is in the wheel well - thanks for the tip. The clearance with the hood will be interesting . Hopefully it all fits with no rubbing. I'm going to cover the actual jake head install in a new thread. This thread will...

    I planned it that way since on my Heater in a Can project had an 1 1/8" hole saw hole that came out at 1 1/4". I'll take luck any day!

    Trick, functional jake brake grenade shifter

    More progress! Baby steps, but still progress. I got the oil line relocated which was involved and was something I've been not wanting to do. A 9/16" holesaw wobbled it's way to a perfect 5/8" hole and the hard line under the dash was soft enough to bend by hand to it's new shape. I was able...

    Trick, functional jake brake grenade shifter

    The relay tucked up real nice between the heater duct hoses and the firewall. I removed a 1" knock out which is in the perfect place behind the rotary switch and just to the right of the jake heads where the wires will connect. It looks like the oil gauge supply line will have to move over to...

    Trick, functional jake brake grenade shifter

    OK, now that my jake brakes have arrived I'm once again making forward progress on the wiring between the grenade and the brakes; particularly the relay that the grenade activates. I'm using a type 191 five prong 12 volt relay and wiring it to be ground triggered as shown in this diagram: The...

    Post 9-11, I assume? Did they want proof it was a dummy or ask for it to be removed? Was the guy with the rubber gloves extra thorough?

    Thanks for the compliments fellas - I appreciate it! I had briefly thought about making these to sell and a few people have brought that idea up, but there is so much involved that it would not be practical - it would have to be a labor of love. My machinist says there's about $300 worth of...

    Trick, functional jake brake grenade shifter

    Pretty close. I will use model 25B if I can't find the 425A, but the advantage of the 425A is that they will work with a divided entry turbo which is more responsive in the low to mid range versus the single entry only usage of the 25B. Even if I find the 425A I don't believe I will repaint...

    Thanks! I kinda went overboard hiding everything and making it look as close to a military option as I could.

    Trick, functional jake brake grenade shifter

    The +12 volts coming into the rotary switch will come from a relay that is controlled by the grenade; battery-->relay-->rotary switch-->jake head So the grenade will tell the relay to activate the circuit and the rotary switch will direct the power on where to go.

    Trick, functional jake brake grenade shifter

    Here is what I'm thinking for the wiring from the switch to the jake heads. I've never worked with diodes before but they're simple and my buddy the electrical engineer says they'll work all day everyday and this is a simpler way to do it than with relays. All 4 of the wires that terminate...
