hey everyone, i stumbled across your fourm the other day looking for tips on installing a TT in a RX-8 for a customer of mine, but no one seemed to have anything written down, so i did it the hard way (starting from scratch), but in the end as far as i know it was working 100% and allowed the user to arm the car with it still running and walk away knowing it's locked and the alarm is armed...... if you're lucky enough to already have a gready turbo kit :p

so if anyone needs this info, i can make up a write up for your fourm on how to modify the factory security wiring and hook it up.... just email me at modsquad@shaw.ca if you would like it, i won't be on this fourm cause i don't have an RX-8 so email is the best way to find me.....

take care
jay

 

I'm interested on how to install. Emailed you.

 

yea, i emailed him to two days ago, no wor d yet

 

He replied to my email. Here's the instructions.

yea i got them yesterday too, but at least the rest of the 8'ers will have these instructions finally! did you start your install, i think i will later this week or in the weekend. We should do a DIY.

 

If you ever come back here Jay, Thanks MAN!

 

This is near the bottom of my future mods. I will probably hold off until I get the tuning done among other things (PWR radiator). At least we know how it's done now. Thanks alot Jay.

Also, he mentioned not being able to find the rpm signal wire... It's the brown wire on the emanage harness. I tapped into it for the e-01 and it works great.

 

I always seem to forget to let the 8 run a little while or I am in a hurry so this mod is #1 for me right now. I started it tonight and am going over to the DIY to start a diy on the install so other 8'ers can have some pics and who knows . . I may learn a few things along the way. Thanks for the tip on the rpm wire.
