Available "Pins"

[2fnloud]

Been reading an noticed with Chrome and the 98/99 full cloned ECUs that there are empty pins for some nifty things. But I have not been able to find a master list of all the "pins" available.


I know that "Pin 92" for MAP sensor and "Pin 91" for WBO2 sensor. Even some rumblings of "Pin 48" for options as well as the "Pin" for the Active Exhaust System.

So I ask can we get a list of what available "Pin" there are and what they could be used for?

Pin 93 (not pin 91) is the fuel tank pressure differential sensor which is only available on the 98/99 cars. I've reprogrammed this pin as a wideband input.

Pin 48 is the FPR solenoid which everyone deletes anyway. So I wrote the code to give the user the ability to control it.

Pin 35 is the vent solenoid which again is a system only available on the 98/99 cars. Since its open, why not use it for something?

Pin 67 is the park/neutral switch. Its normally grounded on a MTX car. Since our cars never came with an ATX (in the states anyway) I've taken advantage of it for the clutch mods.

Pin 6 is something Adam discovered in the manual. Turns out even though the active exhaust was dropped in 95, they never took out the hardware and software to operate it.

There are more inputs and output pins available which I'll be using for future chrome mods.

How many open pins are there?

[Greg E]

Two inputs and one switchable output. There's also the secondary o2s which can be used as 2 more inputs and their heaters can be used as two more switchable outputs.

[2fnloud]

So 4 inputs and 3 outputs seven total, no more no less.

There's all kinds if inputs and outputs. Just a matter of taking advantage of the ones we don't "need".

Do all these unused pins take the same gauge wire and pin size?

[2fnloud]

Greg I am trying to determine how many wires that that I need to add to blackstealth's conversation harness. Better to hack that vs. The factory wiring. That is the sole reason I didn't go with his plug n play option.

Yes.

Adam constructed the PnP ECU with all these extras in mind. Without him, I wouldn't know about any of them.

The PnP adaptor has slots for all of these extras. The hold up for actually using these pins is actually just me now.

There isn't any need anymore to hack wires. Pins can easily be swapped/installed. I posted a video about how to do that in the manual.

OK but I have Blackstealth's 94-95 to 98-99 conversion harness and the following pins do not have wires coming off the leads, they are just coated to prevent shorting.

Pin 33
Pin 34
Pin 35
Pin 39
Pin 40
Pin 42
Pin 43
Pin 46
Pin 51
Pin 53
Pin 54
Pin 55
Pin 57
Pin 60
Pin 61
Pin 73
Pin 74
Pin 77
Pin 79

I am trying to figure out how many of those pins will need wires for various uses when I install the stuff.
