I just got a MAP Enhancer from sprill.com off of ebay, and I am trying to get it installed. I have my generator installed, and did not get any results as far as mpg. So I installed an O2 sensor extendor, and now trying to install this MAP enhancer. here is a link to the part... http://www.sprill.com/NopCommerce/No...hancer-01.aspx

My question is this. There are 4 wires coming out of the MAP Enhancer. A blue one that is by itself. And, three wires one yellow, one red, and one black wire, these three are coupled together. I am not sure what wire goes where. I have found my map sensor. and I know one of the three wires needs to be spliced. but I dont know which wire coming out of the enhancer is the ground, and which ones connect to the splice.

I have read the manual, and still confused. I have also contacted sprill via email with no help.

Please help.
