installing 3 bar map questions

[thewraith1971]

Hi i just recently purchased forum member Dusty_Duster's 93 duster and am looking at purchasing a turbo and getting a custom 3bar calibration....my question is other than throwing the +40 injectors in as he had prepared the car for everything else for stage 5 calibration on the 3 bar map sensor install do i need to modify the wiring harness in any adding wires and adding pins to smec etc.. or do i just get the pigtail connector and solder the connections to old wiring for the 2 bar map sensor?

I like to break the ribs inside of the 3 bar maps so that I can use the stock plug. Some guys will just slot the connector on the stock plug and use it. You could also use a 2 bar map to make a 3 bar map for cheap. There is a member on here who sells those for a good price too.

so basically i am correct to assume no need of adding any wires to factory harness then, just use pig tail or modify factory plug

Correct. It's pretty straight forward.
