Aurora 4.0l / Izuzu 5 speed swap into 88 coupe (Page 46/102) cptsnoopy SEP 05, 03:02 AM I am hoping to mount this little wide band A/F gauge just forward of the shifter bezel. Russ544 SEP 05, 10:51 AM so you'll be using two wideband O-2 sensors then? one for the Holly ECM and one for the guage? or can you run them parallell? It would be nice to have the guage to keep tabs on things. sure a lot easier than having the laptop sitting on the seat andf trying to read it wile driving Russ cptsnoopy SEP 05, 05:07 PM I could use two wide band sensors and controllers, (they even have a dual sensor controller) and I may end up doing that so I can have the more modern wide band controller hooked up to the Holley. For now though, I bought a splitter along with this indicator to have both running off of the same wb02 sensor. I think the indicator actually uses a different output from the wb controller than the Holley but they are both using the same RJ-45 (same as ethernet cable?) connection. The splitter does some magic so it all works correctly. Hopefully the indicator will show the exact same info as the Holley does on the computer screen or I am hosed with this system. cptsnoopy SEP 08, 05:27 PM I did not know which intake air temp sensor to get so I called chrfab.com today and ordered the Holley sensor from them. Allen took the time to chat about the project and the condition of the motor. For now all seems positive.

Just use the stock caddy sensor. the Holly/CHRF harness is already wired for it with the correct plug etc. huummmm.

Russ I was going to do that but when I started looking at the caddy, olds and different years I saw several different options. I called to see what would be correct as I am not sure that they all are calibrated the same. He suggested just using the Holley unit (its for the 950 and is universal). I decided that would be best considering I have not made a fresh air duct/filter yet. The price was just a little more than the stock units. $24 for the Holley unit vs $15 to $23 for the OEM units. I did not have an old one so I had to get one anyway. Charlie cptsnoopy SEP 20, 02:11 AM A little progress is being made. However the humidity has been rather high this summer... Notice the exhaust is starting to rust. The wiring on the trans side of the engine is nearly complete. I finally got around to shortening the wires and soldering them (splicing) together the right length. Still have quite a few more to do. Some of the wires were over 6' too long. cptsnoopy OCT 04, 03:23 AM Keeping the thread alive.... I have been working on the electrical quite a lot but not getting much done for all the time spent. The good news is that most of it is done. I pressure tested the crossover tube I made and all three welds were weeping under 25lbs pressure. I took it out and laid more metal over the joints and now it is holding water fine. Since I had the welder out, I went ahead and fabbed up an exhaust support for the rear. Nothing special but it should help a little bit. Some of the wires bundled up and the rest of the exposed is waiting for the engine to go in so I can get the wire length correct for the pass-through fitting Front and side view of the rear exhaust support.
