signal comes from sender to speedo is processed then sent to ecu. plms does a box to replace speeo

Apparently sometimes they can have idle issues when speed sensor is not hooked up but there are ways around it. If it's not too hard i reckon i'll hook mine up, i want it to run as smooth as possible.
If my mum needs to use the car, i don't want it stalling on her...

and do u think it will effect the ecu if i take a brach to the speedometer.

yeah the ecu does do something with the speed sensor. I think it has something to do with choosing to run on closed loop with the oxy sensor. Plenty of people do run without them with no problems though.

guys. does the speed sensor send anything to the ecu or it is only for the speedometer?????

solenoid on body of car

that first plug that goes to the fuse box does the
speed sensor
reverse sensor
other random sensor on box (netual maybe)
pos to turn alt on (white with red stripe)
and maybe one other thing i cant remember, i can prob have a look at mine if you want a better list,

i kept my fuse box but in insides dont resembale the stock one lol, i moved it all around to suit my requirments, i mainly kept it for the 70a alt fuse and matching wiring so i could upgrade all my headlight loom etc

That gives me some direction, cheers!

But no, i don't have the fuse box.. Sure I can get one if I need to. I assume if its anything like the r33 one, they are fairly big? I want to try and keep the battery in the front if possible so need the room.

Dazza, is that solenoid down on the engine and i just didn't find it? Sorry for the dumb question. I've never worked on a turbo before, only supercharger..

Daveman, thanks for that. I did email him and for me it may be worth the money. 4 wires, definitely sounds good to me. And if it gets rid of the need for more crap under the bonnet and loose wires, I might seriously consider it.

PLMS do a great job, you end up with about 4 wires to wire in and he'll give you all the help you need to make sure it goes smoothly.

If you can justify the cash then go for it

square plug centre pic: boost control solenoid
engine harness plugs into engine bay harness one end and plugs into body harness other end.
engine bay harness provides power feeds from relays for ECU, fuel pump, IGN,.
most other wires are for speed sensor ,A/C, ABS etc
get a diag or you will be totally lost
i did electronic engineering and i needed the diag.
its not as hard as it looks but you need as much info as you can find
if you get stuck PM me
