4th gen semi swap
If i do the full interior swap with gauges and electronics, will I have an issue with the computer? Because I'm looking to do just the interior and wait probably a year and do the drive train.

Re: 4th gen semi swap
if you're looking to do the swap, you'll need to get the LT1-era gauge cluster. the LS1 clusters got its sensor data from the PCM and won't work. Otherwise, no issue, just lots of work

Re: 4th gen semi swap
When I do the ls swap drivetrain, i could just swap over the gauge cluster or would i need to do the full gauge with wires and computer?

Re: 4th gen semi swap
unless you're doing a carb setup on the ls1, you need to use the harness and computer. you'd just keep a few extra wires most of us discard when modding our harnesses. check out lt1swap for the wiring work involved in making an LSx work

Re: 4th gen semi swap
What was the biggest difference from 93-96 to 97-02 camaro/bird dashes? I want black or something closest so i'm trying to figure which era dash i should get and when i do the ls1 swap for drivetrain i want to make sure the cluster and everything match up properly.

Re: 4th gen semi swap
I know it sounds odd, but lt1swap.com has some of the most in depth LS1 wiring info you'll find (outside of Pocket
). The LT1 gauges were driven by switches on the engine, much in the same way our 3rd gens were. The LS1 gauges are not; they use the serial data from the LS1 computer. Without running the LS1 computer, you cannot use LS1 gauges.

Re: 4th gen semi swap
its not a very hard swap. hardest part is the heater cable. wiring took me maybe 3 hours and my trusty multi meter. now i just have all the diagrams and i crossed them over and " printed" my new diagrams. most just matches up to the stock wires colors depending on the yr. i got the lt1 style stuff. when you upgrade to the ls1 style cluster its not even that hard to swap from there.

All 1993-02 Firebird dashes are the same. In fact, the only interior changes at all for Firebirds were steering wheel for 1995, center console for 1997, and digital odometer for 1997. If you want to get picky, later passenger airbags say 'SRS' instead of 'SIR'.
The 1997-02 Camaro dashes/interiors are very similar to the Firebird ones, at least in basic style (still no parts interchange other than maybe the cluster). 1993-96 Camaro dash is very ugly IMO, and completely different from the later one. No shared parts that I know of. Camaro got the same console/odometer upgrades that the Firebird got in 1997 (in addition to the completely different dash/door panels/seats), and then later a new steering wheel in 2000 to accept radio controls.

Re: 4th gen semi swap
nope for 86 iroc. . i run the 95 dash cluster. i think the hardest part was the interior lights. did the swap 3 yrs ago and everything is still working. when you swap to the ls1 just swap clusters. havc stuff is pretty plug and play.

Re: 4th gen semi swap

Also do I need this to get the lt1 tach to work with the ls?

Re: 4th gen semi swap
93-97 v6/Lt1 clusters use the same system (sending units to control gauge output).
98-02 Ls1 clusters use the Ls1 pcm to control the gauges. The pcm gets it's information from sending units on the engine. I'm guessing it's a different value than the earlier stuff.
While possible to use the old style sending units on an Ls1 to control the 93-97 gauges (oil, water, volts) the tach signal may need a box to drive it (not sure on that). For a plug and play setup, an Ls1 cluster is needed, the computer will drive it provided the correct sending units are used.
