Here's the situation, I bought a new Greddy Full Auto Digital Turbo Timer whitout harness and puma and me installed it yesterday but it's not working right. We did exactly what Rob Robinette did (see below) and everytime I remove the key from the ignition, the car shuts off and the Timer won't start. Did we miss something ? Do we have to cut a 12V wire somewhere or just splice them ? Is there any special programmation to do on the Turbo Timer ?

Thanks !

How To Install a GReddy Turbo Timer WITHOUT the GReddy Harness
I installed a GReddy timer last weekend without the 3rd generation RX-7 specific wiring harness. Many thanks to the two list members who were willing to disassemble their vehicles and look at where their HKS timer wires hooked into the ignition switch wires to assist me in identifying the proper wire color codes. I couldn't find any web posting for this procedure; all installation pages said use the RX-7 specific harness which was not available. For those about to undertake this project and do not have the RX-7 specific harness, I post this wire connection procedure.
1. Connect the 12V red wire from the GReddy timer to the black wire with the green stripe on the ignition harness.
2. Connect the blue ACC wire from the GReddy timer to the solid blue wire on the ignition harness.
3. Connect the green ON wire from the GReddy timer to the black wire with the white stripe on the ignition harness. The RX-7 specific harness connects this wire to the black wire with the yellow stripe. These are IG1 and IG2 wires and either will work.
4. Connect the black wire to ground.
5. For the purple speedometer signal wire from the GReddy timer, connect it to the green with red wire on the ECU. To identify it, remove the electrical plug nearest the carpet from the ECU. This is a 22 pin plug with two rows of 11 pins, but not all slots have wires coming from them. Position the plug so the lower left slot is empty.
Count the wires in the top row from the left. The 5th wire should be green with red.

I know but it's too late know, I'm sure there is a solution without the harness....

try disabling the parking brake feature. I don't use it on mine, because it ask for a 12v + , which my parking brake switch gives out a (-)negative instead

One thing I want to know, does the Turbo Timer can be powered ON at anytime even if there's no key in the ignition ?

Does the Turbo Timer needs constant 12V like directly connected to the battery or just 12V from the ignition when you put the key in ?

Thanks !
