Jeff - velocity

Jeff, I need some advise.

I put a prostart remote in a 97 chev 1/2t afew days ago and now the "service engine light" comes on only when the remote is used to start it. I did the tach wire at the coil (white). I just did the basic starter - no locks. The tach gauge shows 0 when running off the remote - probably an acc that is not part of the main acc feed(orange). Is this common? . The prostart has 1 ign yellow ( I connected to the pink ign1) - maybe I should have connected it to the ign 2 (white) altough most GMs use the pink as the main ign wire. Truck runs fine even with the SES light on - hasn't gone into limp mode or anything strange

I am about to do a 98 dodge pick-up tomorrow and in comparing your wiring diagram to that from DesignTech and Bulldog, there are some differences ! Your site has tach as BLACK/ gray and theirs say gray/l.blue. Because these are at the PCM , I don't want to tap into a wrong wire. Your site and theirs also has the acc and ign 2 reversed which won't make a diff.

Any help and verifying of colors would be appreciated.

Thanks, Roy

for the chevy you need to power up an extras ignition wire . it is a white and right next to the starter wire in the connector under the dash.

as for the dodge the tach is gray/black and is at the pcm or you can also use any odd color injector wire .

Ok guys,

That dodge tach wire - is it black with grey stripe or grey with black stripe ??  Will it also need the second ignition wire powered up ??

Thanks for the help, Roy
