Need some help.....Old Skool Greddy Turbo Timer Install.....

Ok, these colors are the ignition switch leads:

ACC is pink with a light blue stripe.

+ 12 is white with a red stripe or just white (AM1 or AM2)

IGN1 is black with a yellow stripe

IGN2 is black with an orange stripe.

I see a problem though. IGN1 is used to run the charging system. Are you sure this thing was made to work with our cars? My TT uses a relay that controls both IGN1 and IGN2.

Maybe the "on" wire on that thing is designed to keep the EFI relay on. If so I need to know if it supplies a ground or +12. You'll still have the IGN1 issue though. Do you have or can you point me to any documentation on this timer?

Hm interesting. Yeah see if this helps you.

If you scroll down, it's the GTT3 Turbo Timer. The schematics and instructions are there.

I'm pretty sure the instructions say if there are two ignition wires. connect Red to 12v, Blue to IGN1, and Green to IGN2, rather than Blue to ACC. Maybe you can verify that from the website.

Damn thing is sideways . Standby while I look at it.....

Ok, I see what they're doing. Odd way to do it though. Seems they're just supplying power to those two line through the timer after snagging it off the hot side of the ignition switch. I designed my timer to simply jump around the ignition switch but in the end it's the same thing.

You're right about the colors. It says the green wire has to go to the IGN side that doesn't drop during cranking. Connect green to IGN2. Near as I can tell you're good to go with that using the colors I mentioned. Do you have those at the ignition switch?

Yep I'm almost 100% positive I do. Thanks a lot for the help Jet. I'm gonna wake up early tomorrow and see if I can get it done. If for some reason it doesn't, hope you dont mind getting a PM haha. You wouldn't happen to know the color of IGN1 would you?

I know this is an old thread, but wanted to make sure I'm looking at the correct thing.

I have an 87 Turbo and I'm installing the Greddy Full Auto TT.

Am I looking at the right schematic as well?
