So a few months ago I installed some innovative af ratio gauge and a oil pressure gauge, I used slot 13 in the sjb as my power source. 2 weeks ago I had to take it to the dealer because the sjb had "internal failure because of the gauges, so now where do I get my power source that comes on at ignition ?

 

auto or manuel trans??

 

Automatic

 

got to bump this because i still have 2 guages just aitting there.
also on a side note i just got code p0340 which i have read and found coulc most likely be the alternator so could that of cause the sjb to go out instead of the guages.?

 

For mine got the key signal off the internal fuse box and with a relay pulled my own power.

 

My bet is on the alternator. I had the wide band AFR and boost gauges plus a power antenna wired in the same way as you had yours on my 2006 and never had any problems.

 

I plan on eventually going scso what alternator is recommended ?
@jimc just to double check you had your gauges at slot 13 in the sjb
