Modding the Wiper Stalk

[lacrssgus14]

Ok, so 90% of the forum please disregard this post, its not really going to be a functional idea for most normal people, lol.

I would like to use my now useless windshield washer button on the end of the stalk as a nitrous or a line lock button. I want to interrupt the signal from the button to the wiper motor so that the button just activates the old washer pump wire and not the wiper motor. Is it a direct link between the two inside the stalk box or is their going to be a separate wire going to the wiper motor?

IIRC it is usually a common ground, then a wire going from the button, to the terminal plug and then though the body to the pump.

Chris, close, but not quite.

Both wires to/from the pump, come from the wiper relay, 1 t's to the stalk. Blue and yellow wire, from stalk, goes to both relay, and pump.

Blue wire at pump "yeah, a blue, and a blue/yellow" is the main power wire --- 20 amp wiper fuse>junction block> stalk, wiper motor, and wiper relay, and pump.

Grounds come off the body harness.

I have an 84 Electrical supplement next to me :D

i bet there's at least one within reach at all times right? :p

I like the idea of using existing unused switches and buttons for more useful and stealth applications, but I think the stalk button is too fragile for a line lock or nitrous. In a race sitiuation it would be possible to break it off once the adrenalin starts pumping. Too often I find myself trying to push the pedal though the floor, and then realize I don't really need to push that hard, full throttle is full throttle, no matter how much harder you push. I couldn't imagine trying to hold on to that wiper arm while squeezing, especially with a boosted 2jz. But thats just my opinion.

I also see that he's running a manual tranny (ACT 6-puck clutch in the sig is a clue). At some point, he'll have to let go of the button in order to shift.

Unless you are running a slushbox, I would say the go-juice button needs to be somewhere closer to the shift lever???

I'm with Frank though... In the heat of the moment, I can see "something happening" to the wiper stalk itself. It's not the beefy'ist lever assembly in the world, considering what it's original design was for. Good idea though!!!!

maybe something like this???

Line lock is only used for pre-stage burnouts at the tack and getting into trouble on the streets. If it were to be used as a staging brake I would be releasing it at launch anyway so would rather be able to click it off on my way down to the shifter for the 1-2 shift. It would be wired with a latching relay, so used as a momentary switch, will not need to hold it in.

I mis-spoke with the nitrous, it would be used for purge not the hit. Nitrous is setup to run off of vehicle speed control through the AEM.

I am still in interior planning stage, so have not started cutting yet. Any other ideas for switches? My fog lights have been re-wired to the headlight circuit, so that switch is wired to the exhaust cutout. The old automatic "pwr" switch is now the nitrous arming switch. I have a 7" LCD in the stereo slot, so no room for extra switches in there.

If mods feel this is better suited to the Interior section, then please move it.

IIRC - Traditionally a line-lock switch is near the shifter.

Be the first to do the 89 Steering column swap, so that the cruise switches on the 89 wheel are active-Good locations for nitrous and line lock, and a nice clean look as a bonus! I'm with others, location/durability would become issues in "heat of moment". Ive got Parking brake modded, so I can pull without it locking-good as a cheapo line lock-but even the simple brake release/reach for shifter for 1-2 shift motion can cause problems for me at the strip-Ive missed shifts/pulled shift knob off doing this.

I've replaced the stalks on both sides (various cars) due to ball bearing/spring failure (the detents). The wiring stuff is easy, but unless you swap the entire yoke (recommended) plan on either luck or several hours (plus assembly lube) to get everything to snap into place. It takes like 5 hands to get everything aligned just right without the ball bearing on the end of a spring shooting across the room.

Also watch out for the differences between years (Cruise control mostly). The pins in the harness out of the steering column are some of the easiest to repin; I was surprised at how easily they came out. Easy if you can read the TSRM electrical diagram (or even better Junkie's electrical Supplements) which by your sig you can.

BTW, it would help us give you a response if you put your car's year in your sig. 82/3 is very different from 84-6 on this. I don't have a mental database of folks' cars (unlike Tanya who told me you have an 85).

I have changed my mind and picked up a switch from ebay to use for the line lock. It is a rear diff locker push button switch from a 93 4-runner. Direct fit into the center counsel and will probably replace my old automatic trans econ/pwr switch. It is lit, so will require ground and hookup into the dash lights circuit.

Now I am on the look out for any other type of factory toyta switch that would be useful. The guy told me that the switch came from 93-97 4-runners, so apparently Toyota used this shape/style switch body for many years.

Still trying to use the washer button as a nitrous purge switch, trying to keep the interior with no non-oem switches present.

[rwago]

Yep, the shape is common for a lot of cars. while in the junkyards look at the 80's vans. they have some really cool switches. I have also found some cool looking ones in cressida's and corolla's. Even other manufacturers used square shaped switches.

The ones in most cars for window washers (big square switch) would make cool nitrous buttons. The wavy lines could also mean "gas flow".
