Ok so Ive got a few questions about the current install. Its a 5177 and its used and came without the harness. I have the 30 amp relay but . . . I don't really know which terminal to hook everything up to . . . example wot switch to #85, toggle switch to #86, battery to #30 .. . etc. Secondly with the FPSS do you have to remove the shrader valve? If so how is this acomplished, and is it necessary? Lastly do you guys route the nitrous line under the car or along the door trim with the other wire bundle? Ive seen it done both ways. Thanks in advance guys!!

 

5177 schematic is below. You will have to remove the shrader valve to use the FPSS. You can get a shrader valve removal tool at any autoparts store for about $1. You can run the line under the carpet along the door trim but that is not NHRA/IHRA legal. I havn't been caught and you probrably wouldn't be unless you have to go for chassis certs. Also if your going through the grommet behind the computer put some convoluted tubing around the nitrous line so it doesn't rub any holes in any of wires behind that kick panel.



BTW: Since the schematic doesn't have the terminal numbers I believe that the orange wire corsponds to #30, green #85, red #86, blue #87. I'm going off memery but I believe that's how it was.
