Remote start guru's...

i have an 03 Dodge Diesel, just installed a Viper 5701 remote start, this is a 5spd, so you know with the new vipers you NEED tach for the RS, i cannot find tach to save my life, i am an installer, so i know what i am doin, just looking for some more input from other installers. i dont have a PCM on the side of the firewall like the autos do, i know where the ECM is on the side of the block, its not a blue/gray like the 04 and up, i have tried multiple wire ( testing ) no dice. i have tryed the Cam postion senor, no dice. you cant use virtutach or voltage, these diesel wont pick it up, i cant use the 454T? the tach generator, it wont sense the signal in enough time, i have been seaching for this thing for hours and no luck, **** i have this remote start and cant use it. any help would be great thanks!

I ran into this problem on a 2002 Ram about a month ago. I ended up loking at the wire diagram for a 2001. Seems odd that your 2003 would be the same, but maybe worth a shot. On the 2001 there is 2 black plugs right about in middle of the firewall, right above the motor, one of them has a white insert in it. In the plug WITHOUT the white insert, there will be a orange/black wire for the wait to start light, and a gray/black wire for tach. Hopefully this helps.

I'm lazy too look up wiring info for the truck, but you tried to grab it right @ the injectors with no dice?

idatalink ADS-AL CA ?

Shows tach output from the moduel.

jakepatch...i have the next body style up, so that diagram is completly diff from mine, i memeber that style, plus i dont have those plug and its a newer design computer/motor

x1le...havent really tried the injectors, on these diesels they are real sensitive and dont want to mess with that, if i have other options

canaan...its not a chipped key ( almost wish it was for this ) so no luck there

according to audiovox tech tips, it should be a gray/black that is in a large harness running along pass side of firewall.

instead of trying to hunt it down, tho, I would probably just grab it @ the uncommon color at the injectors. I've done it in the past with no problems.

10.4 ill try that thanks guys!

The Idata Mod. is what....$80 msrp? Would save you a HELL of alot of headache and time. Should be able to do alarm, keyless, and r/s in no time w/ it.
Those Idata mods are a dam godsend for newer vehicles, and the T-harnesses for some vehicles (toyota?) can have you in and out of a vehicle in less than an hour. Hell, I did full solder on my '04 Avalanche w/ RS-alarm-keyless and it was only 2.5hrs counting cleanup time. Alarm (sytek) wasn't d2d either, had to w2w on the bench.

^ Those t- harness's are nice. Recently did a newer Chrysler and it was pretty much plug and play.

true they are nice and save time, but like i said before it would be pointless for me to do if i dont have a chipped key and everything else is already wired in

is there a neutral safety wire for the truck? if you can find that, Id use that and wire the truck like an auto (thus, virtual tach)

pretty certain that no manual transmission vehicles have a NSS wire. that's automatic only...

Nissan's, Subaru's, VW's do.. and those are only the ones Ive ever looked for
