They are have the engine back in the truck after drilling the cilinders and put oversized pistons in it.

But now they have 4 connectors and they do not know where they belong.
Does anybody from DTR know's where they should be?

It's 1 cable witch is plitted in 2 and both have 2 connectors

Here some pic's

 

Well to be honest I am not sure. They look like pig tails for an aftermarket box of some kind. Did it have a TST on it. Kind of looks like the TST pigtails that go to cam and crankshaft sensors. Where does the other end of the harness go?

 

Those look like the crank and cam sensor plugs for a tst box or a remote start system.
The crank sensor is on the driver side front of the motor right by the balancer.
The cam sensor is up beneath and behind the cp3 pump.

 

What's a TST?

The other end of the harness is going into the firewall at the drivers side just somewhere around 3or4 inches of the top of the firewall

 

I've looked in the owner's manual of the Banks Six Gun. And it's from the sixgun.

I will print the owners manual and give it to the mechanic

 

Well did not know how the Banks Sixgun connected. The TST is a performance box like the Sixgun. Those should be the cam and crankshaft sensor pigtails.
