I am a rookie rem start installer. I have never worked on a vehicle using a mux wiring system. I am installing an Autopage RS-665 and an idatalink Ads-al ca on an 08 Dodge Ram 2500 Diesel. All alarm features work great, however.... my 1st problem is hooking up the 665. Most of the typical wires (i.e. acc 1, ign 1, acc 2, starter, etc.) do not exist. so, getting the 665 to even begin the crank sequence is not happening. I just don't have enough expertise to troubleshoot this install. I did take some 8 ga. wire and ran it from the battery for my constant power, due to the smallness of the wires in the ignition harness. I know I haven't provided very much info here. I was just wondering if there's any info on what to do with some of these wires on the rem start unit. also, I've had alot of trouble with these idatalink modules and the weblink updater. i've tried 4 cables and 2 modules and cannot get any computer to recognize the module. Anyone else having problems with these units? ------------- "It is impossible to defeat an ignorant man in argument."

why dont you start by painting us a picture of how you have things wired right now.

Well, i have the idatalink wire in properly... at least as far as the manual says. As far as the 665, I have the 12volt and ground wires connected. what, on the 665 has to be connected in order for it to send a command to start? the ignition wire is hooked into the idatalink. the ign 2 wire is hooked to the pink/white wire in vehicle. the starter wire and acc wire are not connected. the starter wire on this vehicle is the same as the accessory wire, which is the mux wire. but, when i test the mux wire, it doesn't give 12 volts at any time, like an acc or starter wire would. I don't know why, but i cannot figure this one out. ------------- "It is impossible to defeat an ignorant man in argument."

i did an autopage the other day for the first time so im not very knowledgeable on that but the one i installed needed to have the tach or voltage learned before it would even try to activate the remote start
the mux wire works by sending a ground through resistors. one resistor value will activate the acc circuit and another resistor value will activate the 2nd starter. does your bypass just take care of the antitheft or does it hook to the mux wire also to take care of the acc and 2nd starter also. if not then you will probably need to do this but you might need different resistor values for your truck. dont sweat it that this truck id giving you problems, it is a real PITA vehicle to do remote start on so just take your time and do it right. i will try to check make sure those resistor values are right for your truck. -------------

ok, this should be the right diagram 08 dodge ram
and here is the audiovox tech sheet
Battery LIGHT BLUE/RED (+) IGNITION SWITCH HARNESS
Ignition 1 PINK/WHITE (+) IGNITION SWITCH HARNESS
Ignition 2 PINK/GREEN (+) IGNITION SWITCH HARNESS
Accessory 1 VIOLET/BROWN (-) IGNITION SWITCH HARNESS
Starter 1 YELLOWGRAY (+) AT MODULE UNDER HOOD
Starter 2 VIOLET/BROWN (-) IGNITION SWITCH HARNESS
Anti-Theft Type DAIMLER SENTRY KEY® VEHICLE IMMOBILIZER
Anti-Theft Descript THE KEY SENDS AN RF SIGNAL TO THE BCM MODULE THROUGH AN ANTENNA LOCATED AROUND THE IGNITION CYLINDER
Key Sense VIOLET/BROWN (-) IGNITION SWITCH HARNESS
Tachometer DARK BLUE/GRAY (AC) AT PCM MODULE ON PASSENGER SIDE FIREWALL
Speed Sense DARK GREEN/ BROWN (AC) AT PCM MODULE ON PASSENGER SIDE FIREWALL
Parking Lights WHITE/ LIGHT GREEN (-) AT VEHICLE LIGHT SWITCH
Brake Lights WHITE/ TAN (+) AT SWITCH ABOVE BRAKE PEDAL
Reverse Lights WHITE/ LIGHT GREEN (+) IN HARNESS UNDER HOOD ON DRIVER FENDER
Horn DARK GREEN/ VIOLET (-) IN HARNESS AT STEERING COLUMN
Databus WHITE/ ORANGE (DATA) IN HARNESS AT STEERING COLUMN
make sure to test and verify each wire you connect to because i have had problems with audiovox tech sheets not matching up with the wires in the car -------------

bro, thanks sooo much for the help! you're a lifesaver for sure! i will print all this stuff out for tomorrow. being that the weblink updater was bad and i just got a new one in, i have to get back on this install in the morning.
yeah, i've done a few rem starts, but this one has been the worst thing i've ever encountered in my limited span of time doing them.
thanks again. you've definitely made a new dedicated "the12volt" member outta me!

Is this the same for a 2008 dodge Ram 2500 mega cab.

pretty much the same stuff as my 06 and I'm having same troubles. The audiovox paper that soundnsecurity posted is different than what I have seen so if all els fails, I may have to try that.

well first off your igniton one output has to be connected to the truck the way you say you have it wired the remote start nor the bypass is getting an ignition signalthe idatalink piece needs to see igniton to activate some of its circuits but the truck needs to see igniton to start, so the idatalink piece should be wired to igniton hot same as the output from the remote start not just connected to each other and ended, and ive not had any issues with idatalink loading except before they had the windows vista 64bit operational and my cpu was using vista 64 bit
their product and tech support have been phenominal

I put an Excalibur remote start on a 2008 Ram Diesel. I used the voltage sensing option but that didn't work. I think it's because there are two batteries on the diesel and the voltage doesn't change enough for the remote start to catch it. I used the XK532 Bypass. When you remote start it, the alarm still goes off (even though it's not supposed to). Used a 480 ohm resistor and did it the "normal" way. Is the tach wire the same for the diesel as it is for a "gasser"? Cheers all...R

I have the diesel starting stoping door locks working but I dont know how to put a delay for the start on the diesel. Any place to take a glow plug input?

amended to my last post on the i datlink piece ign only goes to the module and it handles giving the truck ignition due to very sensitive timing of keysense circuit, as to your diesel, i use audiovox and they have a programming option for a wait to start delay in their programing, as the wait to start light is data fed on these newer trucks, does your remote start have an option in programming for a diesel delay? if not youd have to wire in a pulse timer from dei to create your delay i would check with your manufacturer of your remote start and bypass to see how they would recommend doing it using their pieces as there are some very touch circuitry in these new dodges

Well it says it has a diesel delay and i think i just figured it out. If the diesle doesnt have a light because its all electronic(wait to start) then on my prostart you can use a tme out mode which you wire the glow plug input directly to the ignition wire so after 25 sec it will then start to crank.. I had installed a diode with the glow plug wire to my module but i didnt need it cause its a input not a output. The ADS module from idatalink is so slick on a 08 dodge ram we only connected p-lights, power and 4 wires to the harness on the steering column for the key. I will change the glowplug wire later and all should be good for the delay.
