Where is the best place to install the oil pressure, and coolant temperature sensors? (GReddy gauges)
thanks in advance

 

btw this is on a Integra GSR motor.

 

Most people put the gauges on the, ah, pillar? Like on the left side of the driver, the part right along the windshield.

 

I'm not familiar with the greddy guage kits, are they mechanical guages or electric? That will determine what kind of placement restrictions you'll face more than anything.

 

For oil pressure, you can either put the GReddy sending unit where your stock one is and run w/o the stock idiot light, or you can tee off the stock sending unit location for both. The bes way is to run a line to a tee mounted on the firewall to isolate it from engine vibration:



Although some tee right off the block:



Teeing right off the block hangs a lot of weight off the back of the block on a pretty small fitting, and with enough vibration, it could snap right off, which you probably wouldn't want.

For water temp, people often install the sensor in the coolant bleed port(if you have a B series). My D16Y8 doesn't have a bleed port, so I elected to use GReddy's 34mm water temp sensor adapter, which splices into your upper radiator hose. I had to switch to larger B series hoses to fit my PWR radiator, so the 34mm adapter fit perfectly. It was too large for my stock hoses.

 

thanks to those with real answers
where did u tap for the illumination wires?
thanks!

 

I just tapped them into my turbo timer harness.

Red - switched 12v
Orange - 12v ignition(I think I used Ig2)
White - 12v lighting(Parking light fuse works okay)
Black - ground
