I have just installed a td27t-2 into my navara, The factory speed sensor in the navara is by the water pump. but in the 94 td27t-2 it is under the diesel pump gear. The plugs are the same, but when the motor is started the needle starts a 6000 rpm and works it way back down. We reversed the pins in the plug with no luck any ideas??

I had a simalar prob. I had the SD23 and put in a TD27t. The SD sensor picked up one (from memory)pulse per rev and went direct to tacho, the TD sensor picks up 6 pulses per rev and drives the tacho via the EGR 'Brain'. This black box is found in the rear left guard in Terrano's. I had to use one and change the tacho as it was different aswell. Just wire sensor and tacho and 12v + and -


Hope this helps

What did it cost all up for the ERG control unit and the different rev counter??

Nothing, came out of the engine donor truck.

Did you use the whole cluster or just the rev counter part. If you used the whole cluster how did you sort out the millage on the speedo??

So i got a terrano dash cluster and control unit. Is there any way of changing the km on the dash as my cluster reads 175km but new cluster reads 270km???

I used just the rev counter internals, and had to redrill dial face
