Yes i swaped out all three it was along time ago but i think it was nessasary to use the sensors that came with the new gauges. I used SPA duel gauges water and oil temp sensors went in the original nissan positions as did the oil pressure sensor . They where slightly larger than the nissan one so i had to alter the centre console with an adapter plate from eBay. there should be a thread on replacing the oil pressure gauge here some where if you remove the nissan oil pressure gauge i think it was said you lose the low oil warning light of the dash .
