Hey guys,
What is the best way to wire this thing? Someone advised me to intersect the wire to the solenoid but then wouldn't that wire only be engaged when the key is turned all the way??

I was thinking of powering the switch with a 12volt source then conecting to the solenoid??


This is the unit..

that purple wire to the solenoid is already 12v. all you need to do is like your friend said. intersect that wire. and then create a ground from the switch. make sure you use the correct gauge wire or the wires will smoke the insulation and melt.

Incorrect. the purple wire only has power when the key is in the crank position.

There is no ground. If you add one it will smoke the insulation and melt.

Use the junction block on rad support for you source (as long as the fusible link is still there, if not add one) to connect to one side of push button switch, the other goes to "S" terminal at starter. Use at least 10g wire, use a heat sleeve around the wire near the starter. When using the button, be careful as it bypasses all safety devices and will crank even if its in gear. It can be wired through the NSS, but will require doing some wiring under the dash.

Hey thanks Greg,
I had a feeling that was the correct way you described. I have some 10g wire, a junction block (M.A.D style protected by f-link at batt) and a heat sleve hose. The button should self ground.

Yes I thought the same thing about the button being inadvertently activated leading to disaster. Button placement must be accessable but yet functional.

If you have too many grounds in a electrical application will it overload a ground wire and cuase it to "melt"???

Correct

thats the same thing as splicing into the purple wire, and grounding from the switch like i said. when you push the button the 12v is applied. read it again.

read it again.
I did. Im sure thats not what you meant, but its how you worded it, and still there is no ground in that circuit. Grounded at least in automotive terms means going to bare metal ground.

no i wasn't thinking of the right thing. i don't know why i was thinking that'd work. if you changed my "ground" to 12v+constant, it'd work right?
