Engine harness

[nakabrd]

I am installing an new M&H engine harness on my 1970 Challenger. There is a connection near the coil that is a blue wire with a rubber covered female pin style connector. I called the Technical Support at M&H and he said it goes to the distributor. The only wire that I'm familiar wire from the distributor goes to the positive side of the coil. Does anyone know where this wire goes? Thanks for your help, Jeff

Water temp sending unit.

Thanks Detmatt1 but I found the temp sending wire. This blue wire comes out of the harness with the coil wires. It has a straight rubber piece covering the female pin style fitting, not angled like the temp sending connection.

Oil pressure switch.

Thanks leo but the oil pressure switch is near the firewall at the back of the block.

You didn't mention the engine size so I took a guess at a 340, with rear distributor, oil sending unit. More info helps us to help you.

It's 440, 4 speed, Rallye dash with tach.

Is it a lug or round bullet connector it could be the electric choke wire

 

[nakabrd]

It's a female bullet connector.

I'll have to look at mine, I just bought one too but it's still in the bag.

Electronic ignition

I haven't seen a stock connector other than this one for electronic ignition.

Good point!

OP, what's the item number on the harness?

 

[nakabrd]

It's a points ignition, not electronic. Part number of the engine harness is #00220.

HU107E would be the correct engine harness for a 70 Challenger with 440

Is that for an engine harness made by M&H?
