Hey guys I've got a couple questions. Im doing a swap on my 98 GMC. I have a Street and Performance harness. Im using the factory guages so I installed the factor (98) temp and oil sending units. Does the LS computer need a temp sender also? My harness has the transmission plugs also. Do I use the 98 ones or the LS ones or mix them? I was thinking use the stock Neutral safety wires but what about the speed sensor and stuff? Thanks Chris
