cruise control

[Dreamcar]

So my 69 came with cruise control, but over the years my car got robbed of many parts, including the cruise control parts.

I don't even know what the setup looks like. Does anyone have a pic of the parts/set-up. Google hasn't been my friend this morning.

[Ghoste]

There are some recent threads on here where people had photos of the brackets and servo and pretty much all of it.

[Dreamcar]

Found the thread. Thanks!

I was bidding on a cruise control lever but it went a bit beyond what I would ever pay at + $230.

I have a feeling that once I find one, it won't be cheap.

[Dino]

I'm still kicking myself for not buying on a few years ago because it was $75.  That was the cheapest one I've seen since.  I may just have to let the cruise control idea go on this car.  It's not like I would use it anyway.

I hope you have better luck than me.

[Dreamcar]

Good luck to you too. It's funny, my car is in pieces, it needs full quarters, and I'm looking for a cruise control unit. I figured if it's difficult to find and missing from my parts stash, I might as well get it now.

[Dino]

I think you're doing the right thing by getting the parts now.  Although possible, I wouldn't count on prices going down in the future.  The vacuum unit is pretty easy to find as are the brackets.  Be careful when buying speedometer cables.  A lot of the ebay ones are generic and much longer tha the stock ones.  Ihave not seen the brak pedal switch or wiring for sale for a long time but I suppose that can be replaced with one from another model.  The lever seems to be the hardest part to find which funny enough is the only part I really need.

I got a NOS servo on an auction in $80 back in september... but sure was luck, AND was the late model ( 70s ) They usually run in $150-200 rate... 68/69 are a little bit diff, more expensive, but actually works the same than lates... just talking about correctness if you care

I asked a member about his complete set up on his rig before he started the resto.

He threw it all away.

Lifted this pic off of Moparts while back .
It's really shows the major difference between  the 2 different B body servo styles

[Dreamcar]

Thanks for the pic

How far into the 70's did they use that one?

[ODZKing]

I just went through all this actually.  They used the later into the 80's.
I had a 2 vacuum line one and traded it for another which also turned out not to be correct.  I can see if he still has it and trade back if you really want one.  I don't know if it works but I can check. Otherwise I was just going to pick another part at he yard. It didn't have the correct bracket on it as pictured below.  I believe you need the bracket in the pic all the way to the right.

Here are 7 pics I took of the cruise control mechanism on a one-owner '68 Charger.

I guess the dual vacuum tee is tooooooooo... hideaways system ? casuality on 70 they got just one tee becoming the hideaways system electric ?

[ODZKing]

I am no expert, only what I discovered from trying to piece together mine and 73 is different. I believe  they used the dual vacuum to some point in 70 or 71. The second vacuum line went to a switch for the brake cut-off.
By 72 the switch was electronic.

[Nacho-RT74]

eeehm, the brake cut off system is electrical... everything is electrical still on 68/69. The vacuum is used just to pull out the throttle, but the on off system for it is still electrical. Since the brake booster check valve just have one extra tee, I'm wondering if... in 68/69s without Cruise control this tee was used to make work the hideaways ( not from the vacuum tree on manifold ) AND when cruise control was present, the secondary tee on servo served to the hideaways, since is the servo which plugs into the brake booster check valve.

Never have paid attention really on where the 68/69s got the vacuum to hideaways, if the vacuum tree on manifold, or taking it from booster check valve

Manifold tree on mine which I 'think' is original.

Look at the picture below Nacho.  There is a second hose that goes to a switch which is 14-02-32.  That is the brake switch.  I'm not saying I know what it does, I am just looking at the diagram.
According to the 69 service manual that is called a vacuum release valve.  There are only 3 wires coming from the stalk on a 69. I'm reading 1-06 to 1-11 in the 1969 service manual.
"When brakes are applied, switch opens vacuum hose to atmosphere which disengages speed control servo unit." is what it says   
Can anyone verify?  

[472 R/T SE]

I had the same T on my booster. 

Natcho, I'm missing the little "control link" that's used to attach to the carb.  Do you have any?

You are correct.  That hose routes underneath the booster through the firewall to the brake switch.  One of the pictures above shows part of it.  You have to have that it is like an immediate cancel switch when brakes are applied.

[ODZKing]

NOt sure if this is the correct name for this item, but ... This is the one on my 73, is it the same?

[gtx6970]

the 68-69 style system has 2 vacuum ports on the servo , one taps into  the brake booster ck valve to supply engine vacuum. 2nd one goes to the brake swtich . As it's the servo vacuum release on the earlier systems. ( unique to 1969 and earlier systems ) If you look at the 68-69  servo it only has the 2 wire connections .
1970 and later have a 2 wire AND a single wire connection
1970 and later they all use an electrical dis-connect brake switch

The lever on the carb is called a lost motion link. I have some NOS ones around here ,,somewhere .



Mike if you cant find one I'll do some digging and see if I can find them for ya

[Nacho-RT74]

sorry I didn't understand the factory diagram!

got it now! Thanks... nice to learn something new

[Nacho-RT74]

just the one I will use, but I think they began to be reproed couple of years ago! It's the same Odz posted

[71 SE3834V]

I have this unit I don't need and would like to get a few bucks for it to feed the Charger fund. Have more pics. No cables or bracket.
If somebody can tell me how to bench test it I will do so. I have a vac hand pump and voltage meter.

[ODZKing]

The one I pictures is 3769261, Lost motion link is what the book calls it.

why you didn't appear 2 or 3 months ago? LOL

Too bad. I've had this and some other parts sitting here that I've been trying to get listed for over a year. Too busy breathing new life back into my car.
Need a new nox valve? 

[74charger07ram]

How much do you want for that servo?

[gtx6970]

The lost motion links

on the left is an original I think I got off of a 1970 Challenger I parted for it's options , the others are NOS  superseded version,, works the same just approx 1/4" shorter

[gtx6970]

You'll also need the clamp to hold the cable in place,,unique to cruise control applications.
And the brake light switch ( 1970 and later shown , on the left  )

LATE!!! I have got two used servos, but both got the diaphragm broken ( working on get replacement diaphragms )

I have everything of that ready ( including a NOS servo )

the brake light switch is diff too from the regular one, I think due the diameter hole for the switch. I didn't took care realy of that since I have an extra bracket to enlarge the hole.

I HAVE BEING COLLECTING THE RIGHT PARTS FOR YEARS, some have being NOS ( speedo and tranny wires, servo )... now I'm ready
