Guest TurboSedan Posted January 3, 2004 Report Posted January 3, 2004 i'm about to start work on installing my TGP motor into my CS, and i have a few questions (wiring). hope someone can point me in the right direction i'm going to be using my '90 Grand Prix NA 3.1/5-speed engine wiring harness with the '90 TSTE motor i'm putting in (i already sold the TGP harness). i will be using a grainger valve instead of an ECM controlled wastegate, but: 1. i want to know the best way to wire up the intercooler pusher fan. i'm going to be installing both TGP specific fans - i'm assuming the primary fan will work fine just by using the original primary fan connector, but what will happen if i plug the IC fan in with my car's original secondary fan connector? would i be better off by wiring in a manual switch? i will be deleting my car's entire A/C system also, if that makes a difference. 2. what should i do about going from digital EGR to the TGP style vacuum EGR? can i physically block it off and shut the EGR function off in the chip, or would that lead to detonation? i have no emission laws here, and i want to keep things as simple as possible. 3. the AIT sensor. just lengthen the wires? what about the connector? 4. anything else i should know when using a NA 3.1/5-speed harness? TIA joshua Quote
Robby1870 Posted January 3, 2004 Report Posted January 3, 2004 You should be able to just turn the EGR off on the MEMCAL and use a block off plate. Dont know about it causing pre-detonation, but on n/a its fine. I cant see it causing predetonation, since the EGR is really "on" in partial throttle. At idle its off and at WOT its off too. Quote
Guest TurboSedan Posted January 3, 2004 Report Posted January 3, 2004 cool - i know the Turbo Dodges don't use EGR, so other than emissions i don't see why i need it. joshua Quote
god910 Posted January 3, 2004 Report Posted January 3, 2004 1. You simply have to address the fan on/off temps to correspond w/ what you want it to do. A 3 pole On/Auto/Off switch isn't a bad idea either. 2. My EGR is going bye/bye, I wish I could have done it sooner to help in your decision. 3. My plug is broken and comes out half the time. Past that, extending the wires shouldn't be a problem since it's voltage sourced instead of resistance. 4. Don't forget about the second temp. sensor that is in the rad. I don't know much about the diff. between the two harness' but that's the first thing that popped into mind. I guess you'll know if it doesn't run right or you have alot of sensors and no wires. Good luck w/ the swap, I was hoping to be the first to V the 4 door Cutty. Quote
