Ok, just a few quick questions before I start
(installing a Bulldog Security RS-122 Remote Start into
a 1993 Taurus):

Bulldog RS-122 Install Manual

QUESTION 1.
For the ACCESSORY /HEATER motor wires, it says if I
have 2 motor wires (which I do) to connect the WHITE/ black
from the module to both of these wires. Can
I just strip back each of the two wires, and "thread"
them both? Just curious if the 2 wires are not allowed
to touch, and you have to access them in two different
spots, or if this is ok?

EDIT: I called Bulldog, and asked the same question.
The guy said to only use the grey / YELLOW wire, and not
the other BLACK/ green. I did as he said, and the a/c
does not come on when remote started. So I guess I have
to use both?

QUESTION 2.
For the tach wire, it says it's a tan / YELLOW wire
at the ignition harness, or at the coil. I was trying
to find it in the ignition harness, but couldn't.
Should it be going into the rectangle piece that has
all of the constant, start, and accessory wires?
In this car, I don't really see wires coming from
where you put the key in (like I have in other cars).
Any hints? Do I have to take off the steering wheel
plastic cover?

Thanks!

Here's a wiring diagram that I have: check to see if this is what you have:

Notes:
*1 For multi-coil engines the tach is gray/orange at the DIS module on the pass side of motor. *2 Five-wire for non-keyless, negative-pulse for the keyless versions.

Ok, that's exactly the wires that my chart shows.
I was using the Bulldog Wiring Chart.

Here's the update...I don't know if I'm color blind,
or if all of our charts are wrong. Here's what happened:

1. I connected the accessory wire to the grey / YELLOW as Bulldog instructed...nothing happened.
2. I called them back, and then guy said to try the
BLACK/ green wire. I tried that, nothing happened.
3. I even tried using both of these (like the manual
said, but unlike bulldog techs said), and that didn't work either.

Hmmm...then I see 2 other wires in the harness that
could also slightly resemble "grey / YELLOW", although
the yellow part is darker than the one I tried in #1.

So I tried one of them anyway, and lo and behold, the a/c
came on. So, I tried the other, and it worked, too.

So now what do I do? Are those the actual wires that I'm
supposed to be using? I just hope it's not the wrong
wire, but it works anyway. By the way, all 4 wires I've
spoke of showed 12v+ in the RUN position. None showed
12v+ in the OFF position. And only the BLACK/ green
showed 12v+ in the ACC position. Ay caramba!

Now I'm starting to think the 1st grey / YELLOW wire I
tried could be the tach wire that I can't find. I
saw the tan / YELLOW wire by the distributor, and it looks
like a different shade (and size) from this wire, but I'm not sure.
I was unable to test it with a DMM, but they said it
would be in the same spot, and it's not any of the
others.

Ok, I've blabbed enough.

1. Should I just use 1 of these 2 new "grey / YELLOW" wires?
2. Is the original "grey / YELLOW" the "tan / YELLOW" I'm looking for? posted_image

Ok, here's a crappy picture of the ignition harness:

The grey / YELLOW is the wire I tried first but didn't work.
Could this be tach? I know, I have to test it:)

The BLACK/ green I tried second but didn't work is not in the picture.

The RED / light green is the ignition. That's fine.

The two wires labeled grey/"yellow" are the ones that
worked for the a/c (when I used them alone).

I have also run into some FORDS that required all three GRAY / YELLOW wires to be hooked up in order for the ACC to work properly. Have you tried that ?

Something I found ODD about Remot start systems, the few I've used, have all said ACC = AC/Heater. But on every car I've worked on, ACC = Radio, Cig Lighter, and Sometimes Windws, IGN#1 or +12 at "ON" position has been where I have found my AC/Heater - 5 out of 5 Times.

Hmmm....well, no...I didn't try all 3 gray / YELLOW wires (man, that would be tough...it's so tight in there posted_image ).

1. Anywho, when I tried 1 of the 2 other gray / YELLOW wires, it worked.
Is that ok? I'm just afraid that if I leave it, and it's not really
the correct wire, I'll be killing something without knowing it. Can you just go with what works, so to speak?

cdaw: yea, it's a bit confusing with ACC. They say to use the wire that
shows 12v+ in the RUN position, but that was the wire that didn't work.

2. They say the tan / YELLOW tach is in this same spot? Is it in the picture
that I have above, or is that not the ignition harness?

Thanks guys.

Hmm, I just saw this part from your post above. What's the DIS module? I guess it's still inside the engine bay?

I called back Bulldog. This guy said (different answer from every person) to connect 2 grey / YELLOWs and 1 BLACK/ green, and I'll be good to go.

I told him that I connected 1 of the three grey / YELLOWs, and it worked, and he said that's fine, too. Hmmm, is he right?

I just don't want to drain or strain anything that shouldn't get strained.

velocity is right these ignition wires must be all energized your car is a bit tricky at the ignition switch you have multiple 12 volt constants all yellow and you hav e3 ignition wires that all need to powered.im gonna look at my diagram one more time and give you specifics

you should have two gray / YELLOW wires these are both ignitions ,you may even have 3 of these wires.Your tach can be gray/orange.tan / YELLOW,or white pink at the ignition switch. your accesory is BLACK/ light green. your main ignition is RED / light green, your starter is WHITE/ pink. tricky car but dont worry to much about the guage of the wire because in ford they tend to be small thats the way they are meant to work.

in a remote start you want to ideally utilizew all wires that the factory uses in order to not have problems .if ford uses 3 wires use them all that is the right way to do it dont cut corners or ther eusually will be problems. YOU have 3 ignitions this will take some relays to make work corect or if you wanna rig you can diode them but i would use relays.you have only one acc wire but one of those 3 ignitions control your heat so use them all. you have about 5 yellow constant power wires use 2 of them to split the current load. You have one starter thats all. good luck and get a (dmm) its a good idea.

YOU have 3 ignitions:
Well, when I looked under there, I only saw one Ignition wire (RED / light green), so I used that one.

you have only one acc wire but one of those 3 ignitions control your heat so use them all.
I saw 3 grey / YELLOWs and 1 BLACK/ green wire. When I connected it to one of the grey / YELLOWs,
the A/C worked. So I guess i'll use that. (When I used the BLACK/ green, it didn't work....when I used
one of the other grey / YELLOWs it didn't work either. When I used the 3rd grey / YELLOW, it worked.)

you have about 5 yellow constant power wires use 2 of them to split the current load.
got it.

Is the tach wire the only wire that will show A/C voltage (between 2 and 6)? Or would other wires at the ignition harness do the same, causing me to use the wrong wire?

nothing else should show that ac voltage but a tach wire the starter ignition etc will all read dc.

whaT IS YOUR PROBLEM EXACTLY????? I ASSUME THE REMOTE START WORKS THE OTHER WIRES YOU TALK ABOUT DONT CONTROL THE AIR THEY CONTROL MAYBE THE TRANS THE STUFF LIKE THAT. IT DONT MATTER THAT ONE WIRE DID NOT CONTROL THE AIR THAT IS A IGNITION AND NEEDS TO BE POWERED UNLESS MAYBE YOU DONT MIND A WARNING LIGHT ON YOUR DASH IF IT IS NOT THERE ALREADY. MIMICTHE FACTORY AND YOU WILL BE OK DO IT RIGHT AND MIMIC THE FACTORY THATS ALL YOU HAVE TO DO. IF THE FACTORY HAS 3 WIRES THAT SHOW VOLTAGE ON IGNITION POWER ALL THEM WITH AN IGNITION OFF THE REMOTE START TO TRIGER RELAYS. IF YOU TURNED YOUR CAR ON WITH THE KEY AND SOME THINGS DID NOT POWER UP THE COMPUTER WILL THINK THEREE IS A MALFUNCTION AND DISPLAY A CHECK ENGINE LIGHT OR ABS LIGHT, AIR BAG LIGHT WATEVER AND SOMETIMES THIS REQUIRES A TRIP TO THE DELAER TO ERASE.DO YOU HAVE A METER????? I DONT THINK YOU DO GET ONE YOU NEED IT.
