Hello all,

Im searching the net with no recent luck on finding this diagram to install a piggy back unit onto my truck.

Does anyone have a ECU/ECM diagram that you have used to install a piggy back unit such as an FTC 1, AFC/SAFC/SAFCII/NEO onto your truck to tune?

Thanks in advance to whomever can assist.

 

I for one have no idea what all those fancy piggy back units are for.

I can guess but without print outs for them who can say.

Why would they not plug into your OBII plug

 

I highly recommend https://techinfo.toyota.com/techInfo...tis&_nfpb=true

2 days for $15. Download all you want. I have the 1998 diagrams, but the wiring color and pin positions change, sometimes quite a bit, from year to year. Best to get it for your specific model. Also, what piggyback you running, and what kind of boost?

 

im on the edge of the 7th injector kit or running the supra non-turbo 305CC injectors with an Apexi SAFCII piggy back. Stock pulley.

 

Very Helpful thank you
