Trouble locating a proper wire

I need to locate a wire that reads +12V when the key is in both the ACCESSORY and RUN positions but also NOT interrupted when the starter cranks. I have tried my ACC, IGN1, IGN2, and IGN3 wires and none of them give me what I need. My IGN2 is not interrupted when the starter cranks however it has no power in ACC. I own a 2001 S10 Blazer. Any ideas?

What purpose will that wire serve once you have found it? It would help to know so that we can think of alternative ways to accomplich what you want to.J Rilla

You will not find a single wire that does what you want. Only possibility is to use both an accessory wire and ignition wire to trigger a relay.   Wire it as follows: Ignition --->     -----------|--            -------->    86 Accessory ----)      -----------|--     -------->    86 Ground ----------->   85 Fused Constant +12 -------> 87 To device you are powering -------> 30 the ---------|-- are diodes. The stripe side goes toward the relay. Hope you understand my explanation

There is one wire that will do what you want it to do, the main power wire at your ignition harness. It is on in the acc and start position.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

"There is one wire that will do what you want it to do, the main power wire at your ignition harness. It is on in the acc and start position." Not the brown...not the orange...not the pink....not the white....anything left???

Thanks for all the quick responses guys. I'll check out your suggestions right away. JWorm's idea with the relay will solve the problem which I'll use as a last resort if I can't locate a single wire to do the trick. I just got some data from AllData that should also help me.

Auex is right, the only wire that will do that is a 12v+ constant wire. But it sounds like you dont want power when the car is OFF, so you will need to use an alternate method to create the effect you want. If you use JWorms method, you need to make sure you isolate the Accessory wire from the Ignition wire with some heavy duty diodes. That is unless you use 2 relays, with the Accessory wire triggering one, and the Ignition wire triggering the other. Like I mentioned before: Let us know what you are trying to accomplish and we will be able to help you better.J Rilla
