CDL switch

[wesayso]

I have a 1997 40th with the security system. There is a sensor/light where the CDL switch would normally be. I want to do the CDL switch and 7 pin mod. I have several locations where I can mount my own switch but I need to know what kind of switch is the factory CDL. SPST, DPST, momentary on, or what? Anyone know?

Actually you can put the switch into any of the blank spaces you like, and even move other "switches" to get it to the place that you want. The only limiting factor is the length of the wires. Mix/match/move to suit your needs.

Switch-wise you can use a Toyota Hazard switch and re-label...search gives the full details. Cheaper than getting the real one from either CDan or Slee.

HIJACK - I have read and seen many wanting to do this CDL MOD and 7 pin mod, but what other than the Tranny shifting differently does this Modification provide? I have a '93 Factory Locked FZJ80 and i suppose it has the VC in it. Doing the 7 pin and CDL allow for the lockers to be used in 4HI? What's the max speed that the lockers are capable of handling? Per the Owner Manual, IIRC you don't want to drive over 10mph locked.

Someone please shed some light on this. Not to be Naive, just not sure if this should be done or not.

Sorry for the HiJack, just wanted some clarification! (and yes, I have read the FAQ and Slee's Tech write up....)

HIJACK OVER

CDL allows you to lock the center differential while your transfer case is in "HI" which effectively gives you "4HI" as opposed to the AWD that full time 4WD is.

Simply put, equal power will go to your front tires as is going to your rears. Under normal operations (when in HI) there is generally more power going to your rear tires than your front.

Your lockers (FR/RR) will only operate when your transfer case is in LOW.

The 7-Pin mod allows you to unlock the CDL while your transfer case is in LOW, which allows for easier steering (like being back in AWD/Full Time as opposed to true 4LO)



Certain Rav4's have CDL buttons as well (95-97 Dashes):

Thanks for that clearer description yohavos! I have read so many different aspects and some info says that you can use the Lockers while in '4HI' as you described, whereas other FAQ's mention nothing of it. So, again not wanting to hijack, just wanted to know if this was a worth while mod to my 93 with a Viscous Coupler type Transfer Case. Just nothing seems consistent.

Not that this hasn't been answered, but another member (can't remember who) did a video of the CDL install in which he relocated the security "button"

Thanks for your responses. I really just want to know what kind of switch it is (how many terminals, on/off, or momentary etc.) so I can pick up a switch off the shelf somewhere.

The factory switch is plug and play. Install the switch AND do the pin 7 and Voila!! Low range with no lockers. You will find that fact very handy on steep switchbacks where traction is not an issue.

To clarify something here, the very first 80's had the CDL switch however, like fog lights many people would press buttons and not have a clue what the little light on the dashboard was telling them. This resulted in Mr T removing the CDL switch and making the centre diff lock active only as soon as low range was selected, it was assumed that if the typical numbskull never touched the 'little' lever then the diff lock would never be activated accidently. When in high (or low) the power is directed IIRC equaly between the axles, as soon as one axle loses traction the VC (added to later cars) would maintain some driving force to the axle with grip but this was very limited and does not truly lock the axles front to rear.
I have also come a cross one or two cars that have had the lockers at the axles completely disconnected again this was down to people locking axles and then wondering why they cannot go around the corner.

Hope that helps make the muddy waters a little less muddy?
