Did you tie into the stock fuse block for ignition power to the stand alone harness? I would have made an effort to ensure that I didn't alter that circuit during the swap. It sounds like you may have scavenged an ignition feed somewhere for the stand alone harness.

I used the purple wire but I also used the big reddish pink wire hooked straight to the battery to power everything up also I messed up once and even tho I don't use stock shifter it wasn't in park and wouldn't start so make sure collum is in park pink wire battery purple wire to starter also double check all grounds are good

do you have the wiring diagrams for both your 2000 s10 and your specific LS engine and harness? You should be able to plug right into s10 underhood fuse box and be good to go.

Are the relays still on the firewall near the wiper motor the stock harness still there or all stripped out if u don't get it I'll go take pics of mine and help u trouble shoot it

the under hood fuse box is still there and the purple wire come out of the bottom of it is what I thought I would hook to,,but there is no power when you turn the key on it

Im going to need help to find out what I need to cross or hook thgother to get the starter relay working,,all the s10 wireing harness are gone,,so im look for help to get the starter relay working so the purple wire will have +12 volt when you ture the key,,thanks for any info and your time

Do you have a power wire going from the battery to the terminal on the fuse box? If you don't nothing will work.

Don't forget about your Neutral Safety Switch, not exactly sure what all has been removed, but that may play a part in your issue.

yes sir

I have power coming in to the relay but the relay will not kick,,,checked the relay and all the fuses

walkerman233

im thinking its something to do with the Neutral Safety Switch but all that has been removed with the old harness,,,there is a new Neutral Safety Switch plug on the stand alone harness,,but I need the wire from the fuse box of the S10's starter relay to start with the key
