temp gauge dont work after doing a body swap

[doodlebug_289]

i put a new body 87 broncoii on my 88 broncoii and now my temp gauge dont work and i used all the original wiring from 88 I replaced the gauge and the sending unit. does the computer need a reading from that sending to run right or is it just for the gauge?

The guage is separate one wire take the wire going to the sender and short it to ground with the key on if the guage reads hot it is the sender. If your other guages work it is either a wire or the guage itself. The power to the guages should be around 8 volts pulsing. The two wire ECT is for the computer you might try crimping the connector for the sender to fit snug and sand it a little to make good contact.

so if i put a mechanical gauge in it wont affect the the efi system

Not at all as long as the two wire sensor ECT is plugged in and working.
