Hey I'm not an expert at remote starts I've only hooked up one in my life I have two of them one in my Durango & one in my Dakota Dakota was installed by best buy & Durango was installed by pc richards I'm not positive but I think tach wires are the same color on all remote starts and mine are purple the tach wire on the Durango is hooked to the #3 fuel injector wires & the Dakota wire is hooked to the coil but the tach wire is purple look back at installation directions you might have a defective remote start unit remember I said I'm not an expert I'm just going. By what I have I really hope this helped you oh by the way the van has an automatic tranny right? Good luck
The green wire from the tach goes to the negative side of the coil or if its an HEI distributor it will connect to the left of the hot wire going. to the distributor.
I have a 91 Chevy 1500 350 shortbed l replaced spark plug and wires ,distributor cap and rotor button, ignition coil ,and modular under the distributor..and a new battery..the truck is just turning over and won't start..ls it possibly l might have crossed one of my plug wires, l got the print out at a O'Reilly where I brought the parts from..
The input wire to your tach should be connected to the coil. If everything is original there should be a tan with yellow strip wire on the coil connect the tach wire there.
tach hook up for chevy with hei distribitor is 1)white wire ; 12volt source 2)red wire -12 volt ignition switch (+) 3)black wire -battery ground (-) green wire ; to tach terminal on dist. / if it not hei with points just put green wire to neg. (-) side of coil
the way i would check this is too use timing light or a spark tester on the coil wire run motor until it stalls check for spark @ ignition coil if the pickup coil is failing you wont have any spark bare in mind the ignition module can do the same thing so can the ignition coil. the part in the distubutor is called the pickup coil there is couple ways to test this. there are wires going to the coil that come from distubutor one wire pulse fires the coil there is a wire by the coil its a tach test lead you hook up a 12 volt test light to battery positive and check for pulses after the stall ocurrs. also test before stalls so you know what to exspect.if the pulse trigger stop its either the pickup coil or the ignition module.hope this helps Thunderboltz
That should be the white wire rom the dist to coil. eather way you will not hurt the tach if you were to get it wrong. There are only two wires. I would look at the distributor and on the top of the cap there it writing and it will say tach an you can plug it directli into that.
Coming off the coil there are two plugs both with two wires. One plug goes to the distributor. The other plug is the one you want. Tie into the white wire. Sometimes you will find a spade connector already hooked to this wire, hook to that.
