Fuel Pump
So I connect the HSD to the 12V relay, and the FP is a ground that can be ECU ground right?
In the
HSD FP LSD4 header block, you jumper from the
FP pin in the center to the
HSD pin to the left of the
FP pin to select which output circuit to use for the fuel pump output from the MCU. Then you would connect the
HSD pad that is below the jumper (by itself) to your fuel pump relay. The fuel pump relay ground should be connected to your chassis grounding point, not to the Jaguar PCB. You will need to connect the
IGN-12v solder pad to a 12v source since this is used by the HSD output as the 12v supply and for the power to the output LEDs and for the injector LEDs.

So the CAS connectivity should be like so:
RPM1+ goes to the 120ª reference signal (black wire) and RPM0+ goes to the 1º signal?
PRM0- and RPM1- would go to a ground, can this be(or should be) the same ground that grounds the CAS sensor signal?
You can connect
RPM0- and
RPM1- to either the
RPMx-Shield or
Sensor-GND pads as these are electrically the same (they are connected to
GND).

So this is will be the connectivity. I assume the places to connect are the
Ignitor X and not the
IG X one.
Any tips on how to merge the wires from the ignitor relays together?
IG1,
IG2,
IG3 and
IG4 are pads to connect the MCU outputs to the ignitor driver circuit inputs.
Ignitor1,
Ignitor2,
Ignitor3 and
Ignitor4 are the outputs to your ignition system.
IG1 is already connected by a copper trace to MCU Port T2 output and
IG2 is already connected by a copper trace to MCU Port T3 output.
You will need connect
IG3 to the Port T4 (square ) pad in the
Port T4-7 header.
masterkorp wrote:Injectors
So the RB injectors have 2 big common ground wires, I plan on splicing the wires and solder them onto the jaguar, is that ok? Or the ground must come explicity from each injector?
Also why is that surface on the injector ground connectors? Shall I solder the wires onto that surface and the hole?
You will want to connect one injector ground wire to
INJ1-GND and the other injector ground wire to
INJ3-GND. Next you will want to install the 0 ohm surface mount jumpers in the
JP3,
JP4,
JP5,
JP6 and
JP7 positions.
The header labeled
Injectors-IN (what you have in the blue rectangle) is the input to the injector driver output circuits. For your engine you would connect the MCU Port T5 pin (second pad of the
Port T4-7 header) to the first two pins (pins 1 and 2) of the
Injectors-IN header. You would then connect the MCU Port T6 pin (third pad of the
Port T4-7 header) to the pins 3 and 4 of the
Injectors-IN header. You would then connect the MCU Port T7 pin (fourth pad of the
Port T4-7 header) to the pins 5 and 6 of the
Injectors-IN header. This will setup the injector outputs for semi-sequential injection.
You will connect the
INJ1-
INJ6 solder pads to your injectors.

So here I have the following questions:
- Where the power that goes to IAT and CHT comes from ?
- What are those GND and GND connections? Are they extra grounds to connect ground to the Jaguar?
Power for the sensor circuits comes from the Analog 5v regulator and the sensor to ground resistance is measured from the IAT/CHT solder pad to
Sensor-GND.
GND and
GND2 are the main ground connections for the PCB ground/voltage regulator grounds. These should be connected to either your battery ground or at the negative battery cable where it attaches to the head or block.
masterkorp wrote:Wideband
My wideband is
Innovative MTX-L and it has an analog output that can be configurable, I can see where I can connect the 5V (vdc), but where do I connect the ground?
The output from your wideband will connect to the
EGO solder pad and the output ground from your wideband will connect to any of the
Sensor-GND solder pads.
masterkorp wrote:AAC Idle and VTC solenoids
I have no idea what I am doing here.
Would LSD go to the solenoids grounds ? Where do I get the 5V from?
The
LSDx solder pads are the solenoid grounds, the other side of the solenoid would be connected to a 12v source not on the Jaguar PCB. To use
LSD2 with the MCU Port K4 output, you will need to jumper the
LSD2/PK4 header block.
LSD2 is normally used (by default for FreeEMS firmware) for the radiator fan relay if used with the MCU Port K4 output. If you want to use another MCU output to activate
LSD2, then you will need to jumper the round solder pad of the
LSD2/PK4 header to another MCU output (ie: one of the
Port B0-7 or
Port P0-3 or
Port P4-7 header pins). If you want to use the
LSD1 output you will need to jumper the
LSD1-IN solder pad to an MCU output (ie: one of the
Port B0-7 or
Port P0-3 or
Port P4-7 header pins). If you want to use the
LSD3 output you will need to jumper the
LSD3-IN solder pad to an MCU output (ie: one of the
Port B0-7 or
Port P0-3 or
Port P4-7 header pins). The
LSDx-IN solder pads should be connected to an MCU output and the
LSDx solder pads would be connected to a relay or solenoid that rated less than 6 amperes.
You will also need to connect the
OUTPUT-GND solder pad to a high current ground on your engine head or block grounding point to be able to use the
LSDx outputs. You will need to connect the
IGN-12v solder pad to a 12v source since this is used by the HSD output as the 12v supply and for the power to the output LEDs and for the injector LEDs.
Hopefully this clears things up a bit...
