Default Looking for Ideas for reverse lockout

1985 S10 pickup, originally auto trans.
Now LS1 and T56, I want the reverse lockout to work, not using a computer that will help in any way, so I think I'm stuck with
a switch of some sort? Don't really want 2 buttons on the shifter ****, 1 will be line lock.
Does anyone have any ideas other than a button on the dash?

wire it to your brake switch. That way your foot needs to be on brake to get it in reverse

Thats always an option, kinda leaning toward simple button just to get me going for now.

I did away with the solenoid altogether...

It might not be what you what, you want, but it's how I did mine.

Also makes it very easy to hit reverse instead of 5th when going 6-5 and on the brakes.

So what are you using to control the engine ? Or is it carb etc ?

A simple manual switch would be the easiest in the absence of anything to automate it.

Or just push the stick harder to get reverse...

Hey thanks for that, I'm going to check into that.

I am using FAST EZ EFI 2.0, there are 2 configurable inputs and outputs that I just haven't spent
any time on to see if I can use it. I'm just to the point of getting it started, and not top priority at this time.

Yeah probably just going to use a momentary of some sort just to get me rolling for now.

I have not been able to get reverse at all, I did the mid shift conversion, (bench seat which I like),
and i don't know if that is making it harder to get reverse or what, so process of elimination
get the solenoid working is first on that process.

Well for me that has not happened but yeah it could happen. Easy to wire to brake circuit if OP needs to sort out the FAST EFI later

and yeah shift ball with button is another option....or a switch mounted somewhere. It just needs to be ergonomic enough not to be a PIA motion to activate it while typically when one puts car in reverse all arms and legs are busy...

I tried it via brake switch only and it was terrible...there was no resistance at all which made hitting reverse far too easy in the wrong circumstances.

If he has a spare ecu output, then use that, although he'd need to configure it appropriately to work for him.

I have one side of the solenoid wired to the brake switch to provide +12v power to the solenoid and the other to the ecu so it will not ground unless speed is less than 2mph.

So it needs both brakes applied and speed lower than 2mph to energise the reverse solenoid.

.
When I did my A4 to T56 swap I didn't have RLO hooked up and found shifting from 4-5 you cold buzz reverse if not careful as the shifting motion has you going forward and to the right...and if to far right you can buzz reverse. Not ever a problem going 6-5 as I just go forward without any effort pushing the shifter towards the right

Agree best is to have ECU control RLO activation but I was not able to get my PCM to make it work that way so have had it by brake switch for 13 years now. Not one time have I accidently managed to hit reverse instead of 5th if down shifting while at some point hitting the brake. Yeah on paper it could happen, just has never happened for me...YMMV

Anybody have any experience with a time delay relay or ???
Thinking about getting voltage from brake switch then get a ground from a
time delay relay of some sort, like maybe a minute or so, give time to
do 3 point reverse or whatever, then maybe a toggle as well for
ground if for some reason doing a lot of back and forth. IDK just a thought.
I guess it will depend on what kind of timer I can find.

I cannot see what purpose a time delay relay would serve for such an application.

Maybe I didn't splain my thought very well, have a momentary button to trigger a delay relay where I would have
a little time for reverse solenoid to stay energized, I don't think my first thought of brake switch power
is good, just shoot fused power and have the delay relay give it a ground for a few seconds so my hands will
be free then i don't have to push the button again to remove ground.

IMHO if you are installing a "button" to activate RLO...just get a shift **** with a button

Yeah in my very first post I said I didn't really want 2 buttons on the ****, 1 will be roll control.
I just got back in from sitting in the S10 and I have a cruise control button on the
multifunction switch, on the end you just push it in, I may see if I can use that.
I really hope I can use the Fast ez efi thing but it is engine only, not sure how
I could make that work, I haven't messed with that at all yet, just got it back
from warranty on thursday, and need to reconfigure wire harness then reinstall
harness then mount the 2 computer boxes. I do see some company, forgot who,
makes something to plug into VSS on trans to give a signal to the RLO.

my bad, yeah your original post said you were already intending roll control on ****.

I think the easiest temporary, or permanent, way is wire to brake switch. If you figure out a way to trigger via ECU to activate at XMPH later you can rewire it then. Same if there is a aftermarket deal that draws signal from VSS

any manually operated switch, other than shift ball, would need to be in a good ergonomic place so a steering wheel remote switch, cruise control for example, could work if you jumped that switch wiring....I guess depending on what finger/hand would operate it while simultaneously steering wheel in multi turn back up situations, etc. Basically it would need to be seamless ergonomically or could be a PIA

when I was not able to get my ECU to trigger mine I just wired it to brake switch. I never found a situation where I was upshifting from 4-5 where also hitting brake pedal and the 4-5 shift without RLO is most prone to the "buzz" reverse because of the "up & over" shifting motion. For me the 6-5 downshift, even if braking, from my muscle memory shifting motion has always just been straight forward and never experienced a "opps" in 13 years I have had it that way

You have options

Were you using the roll control for launch or just burnout?

Roll control is mostly for daily driving, theres a few little hills with stop signs that I frequent and some of the time someone is right up my
*** at the stop sign, and I find roll control is easy to take off with out rolling back into jackass that's right on my ***.

Yeah ergonomics is why i was looking for a time delay type thing, press the button, then I have a few seconds or a minute or so
to do all the backing so my hands are free to drive.

If the roll control is more for the occasional ahole nuisance who pulls right to your bumper (hate when this happens) consider moving the Line lock to a outboard button either harvesting one you have or a installed switch/button. That's what I have for my LL as I only use it at the track for burnouts after water box. But yeah since I have it I have used it on the street to hold me on a hill because some ahole...well you know.

Anyway then you could use the shift ball for RLO which its use is considerably more than the Line lock use

Not sure if this would work for you on a regular t56 but something to look at. https://www.bowlertransmissions.com/...n-one-harness/
