Jeep Grand Cherokee 2007 wont start

Hi,

i install a Fortin Evo All with a T-Harness. I connect it with the yellow iginiton cable and then with the vehicle.

then in make the install process and the car wont start. On Page 11 is a information about Pin A18 blue/red cable to MUX. But i cant find a cable from the iginiton plug connector who match with the same color.

can you give me a tip for this ??? Which cable must connected ??

Sorry for my bad english :-D
 

Thanks Stefan

Answer 1

You are looking for the ignition harness. This is where you will do the MUX, ignition, and starter connections. Besides for pin A18, you also have some connections to do from the RED connector of the EVO-ALL.

Your MUX wire is purple/brown.

If there is no starter wire in the main ignition harness, you need to do connection C and not connection F

Comments

Yes, and also the connections for STARTER, IGNITION and 12V Battery on the red 6 pin connector on the EVO-ALL as shown in the picture I had posted above.

I do not look through. but I'm not doing all connections to your T-Harness or? the red plug for example the white / red is for starters. which cable color is it then the t-Harness? and i must cut wires from the ignition switch ?? I am overwhelmed with electrics  can someone post a Photo from the ready cable??

Take a good look and pay attention to the diagram. If it gets overwhelming, please have the system installed by a professional.

You are doing connections from the red connector on the evo-all to the vehicle, and also that mysterious MUX wire you were looking for.

A proffesional is hard to find Here in Germany no one Knows fortin :-(  again to understand, I have to disconnect some cables from the ignition Switch and reconnect the red cable ??? Is there also Plug & Play cable ???

Unfortunately because of the year of your vehicle you will need to do the extra connections as I noted in the diagram I posted earlier.
