I have a 93 gs with a aristo swap and im installing a very basic hks turbo timer type 0. All the timer has is a batt voltage reading and rpm if you want.

The problem is after i hard wired everything the timer will work and count down but the motor shuts off but the accessories (radio, windows, lights, fan, etc) stay on for the rest of the count down. Ive tried switching around wires and i even read out the voltage when the key is in the acc, ign and constant power position. And still nothing just the same thing? Does having a automatic change the wiring? Ive installed TT's on manuals before but this one sucks and wont keep the motor running

also all the wiring was done inbetween the key/ignition assembly and the main connector. And the parking break was on to btw.

heres the wiring

HKS Install requirements WHAT I HAVE IT HOOKED UP TO ON CAR
RED-12 VOLT-constant black/Red
Green-12 VOLT-ignition black/yellow
Blue-12 volt-accessory blue/red
Gray-parking green/white
black-ground a solid chassis ground


Can someone please help me out on this im stumpt. Im thinking its the ignition wire that is wrong but but the volt meter says different. also all connections are good. checked everything with volt meter. thanks for the help!

 

No body on this forum has installed a turbo timer. lol.

 

did you ever fix this? i got an apexi turbo timer but they dont sell the harness for the sc300 so im stuck, i have to manually splice into wires but dont know which ones to go into. can anyone help me out?

 

talk to the guys on JZS147.com.au

 

Also i bought the HKS turbo timer harness for the jzs147/jzz30 and it cost 65 shiped from japan

 

Why do you say that? I installed my GReddy turbo timer along with the GReddy harness for our GS. I got the harness for like $18.

 

I did a manual install (no harness)... ill take pics of the wires and post iot... maybe make a 'definitive' writteup about it since many people have this issue...
