How To: Push Button Start
Ok so I've completed this install a few times now. About a month ago now I installed one on my truck, and posted it up. I got a request for write up so I will attempt that here.
First you will need materials, the write up is based on what I used listed below:
S2000 Push Button (New from Honda)
Cruise Control Plug from 92-95 Civic (Others may work, this fits S2K button)
12v 30amp Relay
A few feet of 18ga wire
18ga Female spade connectors
Bolt/nut or a self tapping screw (for mounting relay)
Dremel w/ cutoff wheel and drill ball
Screw driver (#2 Philips or Torx can't remember, to remove kick panel)
Soldering iron and solder
1. First you'll need to remove the kick panel, underneath the steering wheel.
2. Next remove the center trim surrounding radio HVAC controls, making
sure to unplug all of the harnesses.
3. Take the center trim and remove the cigarette lighter.
From here you have 2 options start on wiring or begin reshaping lighter hole for button clearance. I did wiring first to make sure everything worked properly.
4. Gather your wire, spade connectors, soldering iron, solder, electrical tape,
wire strippers, cruise control harness and relay.
5. Cut yourself 4 lengths of wire approx 2 feet can trim later. (I used 4
different colors to help with identification).
6. Take each wire and on one end strip the casing off and add a female spade
7. Plug 1 wire on each of the following terminals; 30, 85,86 & 87 (87a is not
8. Grab your civic cruise control harness and soldering equipment. Heat up
the gun if necessary, depending on your iron/gun.
9. You will be connecting 3 of the wires on the harness to the relay wires.
Black/Yellow goes to wire on Terminal No. 85
Green goes to wire on Terminal No. 30
Black goes to wire on Terminal No. 86
The two Red/Black wires are NOT used you can twist them together on put
electrical tape on the end.
10. Once cooled put electrical tape on all the connections EXCEPT
11. Take your newly connected relay and harness back to the truck. Mount
your relay somewhere ( I used the metal brace where the hood release
12. Pull the harness up to where the cig lighter harness is. You will need to
cut the plug off of the lighter harness and strip the ends for more
soldering. (Wire colors are Pink/Yellow and, I think Black).
Solder the Green/30 wire to the Pink/Yellow which is +12v.
Solder the Black/86 wire to the other (Black) for ground.
14. Now you need to be brave because you will be cutting some factory wires
in your truck at this point... Well at least one, the starter wire. This is a
yellow wire in the harness under the steering column. Once located CUT
NOTE: by cutting this wire you will no longer be able to start your truck by cranking the key it will not engage the starter. The key will have to be turned to on then press your button to start. You CAN keep the ability to start by cranking the key if you SPLICE the yellow wire instead.
15. Once cut you should have one remaining wire unconnected from your
relay (Terminal No. 87). Connect Terminal 87 wire to the yellow wire
running toward the firewall.
If you connect to the wrong side of the yellow wire you will get a click of the relay instead of your truck starting.
16. Take your push button connect it to the harness turn key to on and push
button your truck should be purring nicely.
17. Unfortunately you're not done, turn off your vehicle unplug the button.
Take the button and your center trim back to the workbench and bust out
18. You will need to enlarge the lighter hole a little as well as make 5
grooves so that the button will fit.
CAUTION: take your time as well as test fit VERY often. If you cut too much away the button will not fit tightly and will make the finished product less than factory-like. You want to have to force the button into the hole for best fit.
19. Once you've got the hole shaped pop the button in, take your center trim
back to the truck. Plug the harness into the button, as well as your
remaining harnesses. Put your center trim back in and TADAAAA!!!
Hope you enjoy your new bling!
:rep: for the write-up with great PicZ.
This looks so cool and appeals to my nerdy sense!!!
I've actually always wanted to install either finger print ID ( you can buy them for gun cabinets and such, so am guessing you can get them for truckS too). I'd like finger print ID or keypad for ignition then a start button. Only because I live in a fantasy world where my ram is a lot fancier than it actually it lol
Just curious, what did you pay for the start button and did you buy it direct from honda?
get that H word outta here!:str:
some mopars use the push botton start to (i know the r/t and srt challengers and i think the srt rams) or you can even buy a momentary pushbutton from a parts store and probably radio shack.

Trying to follow this install but i only get power to lin 2 and 3so it lights up when i push the bitton notbing happens how can i tell if its a bad swith what dose the switch do any help thanks
help i have power to pin 2 and 3 but pin 1 nothing or 4,5 nothing no continuity light works is the button no good ?is the ground 86 on relay ithink write up says 86 pic shows 85 thanks
Going to try this!
Hey guys just go buy a 10 ............ Sorry couldn't resist it Bud.
Does it start without the key? Or does the key need to be in the ignition? orr?
