Help needed with gauge wiring

Here is the scenerio - I am thinking of putting an LS-1 motor that I have in my 95 Mustang. If I do so I would like to keep the factory gauges if possible and was wondering how to interface the two and get them calibrated to work properly. I am guessing that they use a (Mv) signal (?) and as such would I have to find out what the range/impedence is on each or would I just be better off going to an aftermarket set such as Autometer or something of the like. Any and all help and opinions would be appreciated. Cheers !!!

Jim C.

senders

Doc here:

Pull the senders off the old engine (the one that came in the car) And see if they will mechanically fit into the LS~1 block.

If they won't Measure them with a DVM for resistance, then measure the ones in the LS~1 Block...are they the same? If so your good to go...If not:

go to the autoparts store and try to match a resistance reading up to the car's original senders to fit in the LS~1 block.

If none can be found, go to the hardware store and look for an adapter (block to sender assuming the sender is smaller) BUT be advised, in the case of temp senders..

The bourdon tube MUST be in the water flow, not recessed...else it will read grossly in error, or an air bubble will live there and report high all the time..(senders can't read air, and moving water is HOTTER than still water)
