With a B18 from a 92 LS, into a 91 LX civic, using 92 wire harness and ecu, will my factory gauges work.

 

yup

 

What, you want to run the B18 wiring harness? Good luck...

 

i'm in the process of doing a ls swap into my hatch and i heard that i could just pinout the ecu. just get a helms manual for your ex and one for a teg. if you decide to stick with the harness than good luck cause it's gonna be a MAJOR PIA!

 

Easiest thing to do is use your complete factory wireing harness, fuel injectors, and computer. You can get your ecu chipped with LS fuel/timing maps. Pretty much
the only thing you would need extra, is a 90-91 ls distributor (see sig ).
