I just bought and edge ez and i all ready have the tst power max 2 installed on my pickup. I am wondering how to stack the ez along with the tst. if anyone knows of where i can go to look at some pictures that would be great too. but if anyone can help i will take it in. I drive a 2000 cummins if that helps anyone. thank you

That will be a nice stack for you, not overpowering, but will enhance the driveability of the truck. I believe all you have to do is plug the EZ map harness to the back of the TST harness, then plug the stock harness into the EZ harness, finish your connections, and you are ready to roll. The EZ does not pierce the pump wires, so there is not much to connect. Make sure all connections are good and clean, and you will be ready to roll.

The TST taps the injection pump wire, the EZ plugs into the data link connector. The only common point they have is the MAP sensor. Unplug the harness from the MAP sensor, connect the TST directly to the MAP sensor. Then plug the EZ into the TST harness, then connect the factory harness to the EZ plug. By doing this, the TST sees the boost directly off of the sensor so you get full fueling. If you plug the EZ into the sensor first, then the TST sees the clipped voltage reading from the boost fooler in the EZ so the TST will never see more than 20psi.

Will the Ez work as a timing device if the map sensor plugs on the EZ are not plugged in at all. The only connection for the EZ would be the Data Link port and the TST box would be directly connected with the map sensor or do you need to run the EZ box map plugs in line with the TST map plugs. Would it be TST connects to the side of the motor, then you plug the EZ to in to the other end of the TST connection then plug the other end of the EZ to the factory sensor that was originally pluged into the block?

Thank you for the advice for the stacking. haha i posted that then the next morning i looked at it and it was a little simpler than i had thought. but i notice that my Data Link is a flat 3 prong connection. which is the 2000 connention. and the ez i got came off of a friends 98.5 with the triangle connection. So am i screwed there or can i get ahold of edge and see if theres a connector that comes with it. or what should i do, if you know, if not then thats alright, I might just sell it again and find the right one.

You should be able to get an adapter from Edge to connect a 98.5 box to a 2000. It was the 2001 and 2002 models that had different voltages on the MAP sensor that required a different box.
