Hi was just thinking about the dubble vss i have.



Do i really need it the electric speed sensor that goes in at the transfer case?
can i just use the speed cable and just let the electric connector from the transmissiom.

The VSS tells the computer how fast the vehicle is moving. The computer then uses that information, along with inputs from all the other sensors, to control the spark timing and fuel delivery. You do not need the VSS to make the engine run, but you may experience some hesitation or stalling. It won't hurt anything to run without it, but if you start to have problems such as a rough running engine or stalling when coming to a stop, I'd recommend hooking it up.

ok thanks, i think i will just mount it anyway just to be on the safe side

i finished the exhaust today and took the beast for a spin man the power is unbelievable,definitely worth all the stress and hard work.

just cant seem to get the back up lights working
i had wired up the brown/white wire to the back up light wire brown/lihgt green on the c100 connector but with no success.

aslo i managed to get the vss connected up i had to make an adapter so i could use the old speed cable



now the next thing i connect was the vss these three wires
violet/orange = not needed
brown yellow = ground i need this acorrding to the link, post 142
white/orange = and i need this to, Sensor return (signal to PCM)

Update:
so ive got left to do 4WD transfer case linkage ( not to sure if im going to use the yj or xj set up)
ordered a new fuel gauge http://www.summitracing.com/parts/sun-cp8219 (coming next week)

and still no working back up lights

SLO Ken can you explain how i should connect the back up lights,
theres defintly somthing im doing wrong

what i have done is connected the brown wire (back up lights) to the c100 connector wire A15 brown/light green,
the yellow wire i haven't got a clue you said run start but this wire is coming of the yj bulkhead connector i tried that and the engine started up actually both of these wire are coming of the bulk head.

Have you compared the figure in post 149 to your YJ? That figure shows the yellow wire connected to position C6 of the YJ bulkhead connector. The brown wire is shown connected to G6 on the YJ bulkhead connector.

The backup lights do not need to connect to the XJ harness at all.

Yes, you had them labeled correctly here... the C6 and G6 refer to the YJ bulkhead connector positions.

I'm confused about why you are trying to connect the reverse lights to the XJ harness... Yes, A15 is the reverse lights circuit for the XJ, but your YJ lights are not connected to that circuit. They are (or should be) connected to the circuit at G6 on the YJ bulkhead connector.

Try this... On the engine side of your YJ bulkhead connector, put a temporary jumper (or temporarily twist the wires together) from C6 ylw to G6 brn. This should make your reverse lights come on anytime the key is in "run" or "acc". If the lights come on, then connect the ylw to ylw and brn to brn on the transmission harness. Now the lights should come on with the key, and the transmission in "R". If not, check your reverse switch at the transmission. The switch should be closed when the transmission selector is in "R", and open in every other position.

If the lights do not come on during the jumper test, unhook the jumper, (or untwist the wires,) and check the ylw for 12V(+) with the key in "run" or "acc". If this is good, then check the bulbs. If they are good, then there is a break or short in the wire between the bulkhead and the lights. If you do not get 12V, then check the "turn/BU" fuse in the YJ fuse block.

The NSS wire is Black, not Brown...

It should have been connected to the G terminal on your original YJ starter solenoid. (see .pdf attached)
