Basic pinout for the bosch 88 pin plug intended for universal use.
## NOT COMPATIBLE WITH ANY PNP APPLICATION
A stupid attempt to create an 88pin base board by monday....
Tasks for after all other pins have been definned:
Pin 8 Check engine - LS9
Pin 11 Throttle angle signal to the ASC - Check signal, copy of TPS?
Pin 12 Lambda 2 - Narrow band, Rev 2 job
Pin 13 Lambda 1 - Narrow band, Rev 2 job
Pin 19 Secondary air pump relay - LS? Rev 2 job
Pin 36 EVAP canister - Low side 10
Pin 37 HEGO relay
Pin 41 MAF signal - AN11
Pin 42 Vehicle Speed - Rev 2 job
Pin 46 Ti signal - 12v? Requires pull up but low side triggered
Pin 47 Tacho (5v) - Lowside trigger
Main power switched by SS relay on board so unit is not powered direct from the key.
Relicates OEM power feeds.
VR conditioner on board for crank sensor
Additional Low sides on the board
IGBTs on board
All AC control reserved for a Rev 2 board
