I bought a J_o_t (dyno tech) map switch harness and hooked it up as instructions said... Dont work yes in tephramods it is turned on, thresh hold is a tad over 3v

Than the wire in pin came undone so i tried soddering it in and kept popping the wire off.

Id just like to get it to work any help is much appreciated.

 

What value did you set the Alt-Map switch option to in the 'Enable/Diasable' TephraMod list? It should be set to 1.

Yes it is set to 1. Threshold is 3.04 V as well.

 

Is the Red light turning on when you flip the switch?

-Jamie

 

Same problem here. Led lights up but no map switching happens. I've tested voltage at pin and its right at 4.xxx while setting my threshold between 1-3v. It worked at one time then stopped.

 

No my led isnt even turning on.

 

Then the first thing you need to do is triple check the wires you tapped for power & ground. If you have a multimeter, confirm whether or not you are getting 12 volts on the two wires you tapped for power and ground.

 

With key in the on position, correct?

 

Yes, with the key in the on position. When it's in the OFF position you should see 0 volts.

 

Could i use the power (red) and ground (blk) wires from the cd player to tap into?

 

You can if you want to. Although there is no reason the wires shown in the diagram wouldn't have power or ground since the ECU needs those wires powered to function properly. I generally try to use the ground indicated in the diagram to minimize ground loop noise.

 

Hrm well is it the the solid black wire or the black with grey?

 

Are you installing this on an evo 8 or evo 9? I know it won't work on the 2005 Dodge SRT-4 you have listed in your profile lol.

 

Lol yeah sold the srt 4.. Need to update my profile. Its going in a 06 evo 9

 

Also do you have extra pins? Mine broke off the wire.. Please let me know where i can buy one and if you can a diagram showing what wire the pin goes on whats the power and ground. if you could id appreciate it!
