i have a 99 dodge cummins auto took the edge box off disconnected the lines and red wire off the pump what connects to the red line? i have no power only building 3psi and there is a vacum line that looks too be off im not sure casue its been off for quite some time when i took the box off was i suppouse to plug something back up? any help please? sitting in drive way with no power

 

you plug the map sensor back in?

 

all we did was dis connect the chip we just noticed the line un hooked today its always had plenty of power but whats the red wire on the injection pump was we suppuse to re plug anything back up?

 

x2 on MAP sensor. Where does the red wire go?

 

it threw a code of p0237

 

That's a MAP sensor code.

 

i checked the code and it says Turbo Charger boost sensor A circuit low. Im new to this motor so could you please explain what that means and what i can do to fix it

 

Last time, it's the MAP sensor. Manifold Air Pressure. You would have disconnected it when you pulled the chip off. The factory engine harness MUST be plugged back into the MAP sensor. There are 3 wire in the harness for it, all go into 1 plug.

ok found two plugs behind the fuel canister a female with two prongs and a male with three. Im sorry for the aggravation but i need help knowing what to connect to what but i do understand the diagram.

 

The male with 3 goes into the MAP sensor.

It will look similar to this. There are 3 different styles of connectors between the years of 98.5 and 2002.
