Wire identification - top of the valve cover

1238 49
Hey there - I inhereted this beast from my pops a couple years ago. Finally saved up the money for the 4x4 conversion and fresh paint and body work. She's always ran great but after getting her back from the conversion she feel's like a slug. Planning on having her looked at soon by Sin City Diesel out here in vegas. I'd like to get 3k gov springs, have the fuel plate adjusted, and the fueling screw set / possibly timing set to 16°. I want her to be reliable above all but she's not boosting nor putting out any black smoke like she used to. I think she tops out around 18-20lbs where are before she'd hit 30lbs with no effort. Not that I'm after smoke but its something I noticed it doesn't do anymore. And possibly not going into overdrive, but this is a 3k built 47rh so not sure where to start. Anyway when browsing under the hood I noticed this wire...curious if anyone has any input what it's connected to and or what the heck its for. If you made it this far - thank you lol. This whole thing has been a journey. When she's back from paint in mid october i'll post some photos. 285/75's tomorrow after work!

Anton - if my pops had an exhaust brake installed on this would he have had 60lb springs done too? he always had work done by reputable shops, spared no expenses and kept this thing on the reliable side above all

Most exhaust brake manufacturers highly recommend 60 lb exhaust springs so it "should" have them.

nice! so 4k gsk, even with no intention of going that high shouldn't be an issue. so as i'm learning i'm leaning towards
16° timing
#6 fuel plate
230hp bosch injectors (440$ on rockauto)
4k gsk

No, still an issue. The exhaust brake manufacturers recommend +60 pound springs on the exhaust valves ( only the exhaust valves).

So unless someone went above and beyond, the intake valve springs are likely still stockers.

Can’t help with labor hours estimate, I do my own work that way I know it’s done right. The downside is it usually takes me way longer than I expect.

Injectors are classified by hole count, the size of the holes and the spray angle. What I believe you are looking at are marine injectors, with the wrong spray angle for the piston bowls we have. 230hp is a meaningless description.

Is the boost reference hose connected to the AFC? With that low of an EGT you aren't fueling much.

Here's a picture of the boost reference hose, is just a little plastic hose that sends boost reference to the AFC. Without it the AFC will always think that your not building boost and hold the fuel rack position back so as not to cause black smoke.

Pretty sure thats a 24 valve injector..
Corrrect 98-02

In addition it is only the nozzle. Complete 24 valve injectors cost way more.

If your sure you never want to go past 350 hp, then stock 97 manual trans truck injectors will work just fine (those are 5 x 10.5) . If you'd like to leave yourself a little room for the future (because the desire for more HP never really stops), then a 5x12 is a good choice as well, something like this;

Can't help with the auto trans questions, the only thing I know about 2nd gen automatics is that I don't want one.
