I'm swapping the gauges out on my 91 Camaro (305)...Originals were electric and Canadian (metric)...I'm installing mechanical gauges which also have warning lights...so each gauge actually needs two feeds: one for the mechanical sensor, and one for the electric sender to the warning light.

My original gauges did not include an oil temp gauge.

Where/how do I connect these to the block?

I've currently got a water temp sender on the driver side, near the exhaust ports, and an oil pressure sender just above the oil filter.

Last year, I yanked the EFI and put on a carb...I've now got two old unused senders on the passenger side (one between the exhaust ports, one down lower) - but both of these appear to leak coolant when I loosen them.

My Edelbrock Performer RPM intake manifold also has two brass plugs on either side of the thermostat housing. I'm assuming these are both water temp sensor locations??


I need to hook up the following:

1 mechanical Oil Pressure feed
1 mechanical Oil Temp feed
1 electric Oil Temp warning sender
1 mechanical Water temp feed
1 electric Water temp warning sender

I figure I can satisfy two of these with the two working water temp/oil pressure senders I currently have.

Where should I hook up the remaining:
2 Water temp feeds (one mechanical, one warning sender)
2 Oil Temp feeds (one mechanical, one warning sender).



I feel really stupid that I can't figure this out, but I'm looking for a reliable, clean set-up... (This is an SCCA A-Sedan Camaro I'm building...)

Thanks for any help.

 

they will minimize wiring and fittings.

 

Yes, I'd considered T-fittings...

I could certainly do that for the water temp - using a T to feed both the mechanical gauge and the electric warning sender.

However, for the Oil Temp & Oil Pressure, I'd end up needing 3 connections (Oil Temp Gauge, Oil Temp warning sender, and Oil Pressure Gauge - the Oil Pressure warning light sender is actually connected at the back of the gauge).

The only "oil port" I know of is my current oil pressure sender unit located just above the oil filter...it's pretty crowded down there and I'm not sure I can cram a T fitting with 3 branches on it down there.

Are there any other ports to use for Oil Temp or Oil Pressure??
