The only thing needed to wire HEI is a good positive wire. It needs to be from a wire that is "hot" when the key is turned on...but not when it's off. Use 10-12 gauge wire. Nothing smaller than 14. Run that wire to the positive side of the coil/cap. There are two possible places to run this....but you will find one is marked "tach". That's for the signal feed for a tachometer. Everything else in an HEI is self contained.
What else can I help you with?
Plug wire to HEI distributor diagram?
If it is a early model HEI. Then the inginition coil is bolted into the top of the distributor cap.
Can a disconnected or broken TACH wire from the HEI distributor cap cause a '79 trans am not to start?
Yes, a disconnected or broken TACH wire from the HEI distributor cap can cause a '79 trans to fail to start.
How do you wire a 1979 Chevy 350 hei distributor?
You need to run a switched, full-voltage wire to the "bat" terminal.
Is the spark plug wire placement the same on a points distributor as it is on an HEI distributor?
Yes
How do you change points distributor to electronic distributor on 72 Monte Carlo 350 engine?
The original wire that goes to the + side of the coil will either be a steel wire or have a ballast resistor inline to cut the voltage to the points. You don't want that with an HEI. Either substitute a copper wire for the steel wire, or remove the ballast resistor and install the HEI.
How do you set timing on a 1988 Corvette Non-ZR-1 and is the tan black stripe wire that is supposed to be disconnected from the ECM part of the 4 wire plug that connects to the HEI distributor?
== == need to set timing on my 1986 corvette after replace hei
How do i wire an hei distributor to a tbi harness?
You can not, it is a complete different type of Distributor. And engine will not run
Will the distributor plug wire set up be the same for HEI ignition and non HEI Not sure of the year Chevy 350?
The wires are different - HEI ignition wires won't work in a standard distributor - they all go in the same relative places though.
Do they make a hei distributor to fit a 1967 Chevelle?
Any '74-'80 Chevy HEI distributor will work. The biggest thing you have to do to add HEI is to run a larger positive lead to the coil. The small gauge wire running to your stock coil isn't large enough to carry the proper amount of voltage for the HEI coil.
Where does the fabric coated resistance wire attach inside the car if you are converting from points to a HEI system and need to replace resistance wire with 12 gauge stranded wire?
eliminate the resistor wire all together but you want to run a new larger 12 gauge wire into the same circuit , in order to do that you need to take the fuse box down inside the car and you will see where that resistor wire ties into a big wire in the fusebox, it comes from the ignition switch, you need to tie into that big wire with your 12 gauge wire that you have run from the HEI.
On a 1987 Chevy pickup 350 what wire is used for a tach not hei?
For a 1987 Chevy pickup with a 350 engine and a non-HEI ignition system, the wire that is typically used for connecting a tachometer is the green wire located on the distributor cap. This wire provides the signal needed for the tachometer to work accurately. Make sure to consult the vehicle's manual or a wiring diagram to locate the specific wire on your truck.
Where is the tach connection on an 87 Pontiac hei ignition module?
It's the wire coming from the negative side of the coil.
