1991 dohc

[fastrf]

i have a 91 dodge stealth that i just bought. when i got it it had a dohc coverted from sohc. my issues are, the tach doesnt work it has the manual speedo cable. everything seems to be plugged in. where does the tach get its signal from? the maunals arent very clear. also the oil pressure gauge doesn't work. when it tests, it tested as a bad gauge cross my fingers about that one. thanks.

If you still have the SOHC tach (6k redline) you need a DOHC cluster.
