Not understanding the direction in Razors kit. Is the TPS/MAP harness need or do you just splice into green wire on stock harness at the map sensor and run that wire into the PAC in the car?

Stock harness stays unplugged if using the harness supplied with the kit correct?

Hope I made that clear....
 
use the harness ,
it was meant to help those with digital dash and gnx style cluster but even if your car is analog dash you cant trust the 5v signal to the map because its coming from the old tach boost module in the dash and few of those even work correctly
the harness pulls the 5v for the map from the tps ecu circuit so its a much more stable voltage

you dont need to plug the original map connector to anything but if your boost gauge in the dash cluster seemed to work you could leave your old 2bar map connected with a vac source , although with alky youll be maxing that gauge out since it only goes to 15psi ,
 
Yup, I installed that harness when putting in a new pump at the races. Almost plug n play if you have the green wire already run.
