5.3l with ls1 intake ...which harness to use ? Got a 5.3l 99 truck motor I wanted to put an ls1 intake on. I was gonna use a painless harness "maybe" but I dont know what to get. Will a truck harness work with an ls1 intake. What are most of you guys using in this combination ? I have the truck harness but I know the reluctor is different for the 5.3l and 5.7l ls1. Any advice or knowledge would be helpfull. Thanks
as far as the harness, the car injector plugs are different then the truck injector plugs and some of the routing may be different, as far as where the alt is, etc. are you using the truck acc. and just putting the ls1 intake on? and if you dont mind me asking, why do you want to switch? if for hood clearance you may have to move the alt too
As LScustomers stated, the injector plugs are going to be different. Also, the location of the MAP sensor is different (Truck is on top of the intake and the car is on the back). Not sure what you mean by the crank reluctors being different. They are both 24x engines. Our harness HAR-1012(4L60E transmission) or HAR-1013(T56/TH350/TH400/Powerglide) will work for your application with the car intake if interested.

I have no reason other than Cosmetics/ and I was offered a car intake for free.
Heres what I got : An 88 monte carlo, A motor with only a/c bracket and an idler pulley and tensioner and no accessories, A truck intake and oil pan and wiring harness and computer. I was gonna make my motor mounts because I'm running the 200-4r thats in the car, so the motor will end up where ever the trans puts it. I'm on a budget so it limits everything. The painless harness was offered to me at a very good discount.
I'm open for suggestions / knowledge on fitments of which brackets and accesories will work. I've done alot of research and have not really seen to many g bodies that run the 200-4r trans in the stock location.

I'm definitely interested in seeing your price for the harnesses. The HAR-1013
I thought the reluctors are different between the car and truck. Or early and later yr. engines. I guess you cant believe everything you read on the internet..lol

Thanks, thats good to know. I was entertaining thoughts of using the qwik brackets. I dont mind buying a new alternator and power steering pump to fit whatever brackets i go with so it kinda works out good. The only crappy part is that here in hawaii ls1 accessory brackets seem hard to come by from junkyards. They wont sell anything off the motor. Complete motors only. which might be a good excuse to buy another motor which i'm sure will fit nicely in my 69 chevelle.

Ok, My concern was if I was to order a painless harness which one would I want.. Damn I guess I shoud just set up my factory truck harness to work with what ever intake i end up using. Did you set up the factory truck harness your self ? If so do you have any reference material on doing that ?

this 4 part shows how easy it is, and if you had the car harness like me its even easier

but again, the truck intake injectors and the car intake injector plugs are different, so which ever you use, you just need to make sure you put the correct plug ends on... as shown in the video... i did my car harness and it was fun and easy, with the help of this site and lt1swap.com's info
Nic,
Reluctors are the same on car or truck for Gen III engines.
LS,
The adapters that we have are for EV1 to EV6 setup. You will need adapters for the Multec to EV1 injectors. We dont offer that type of adapter. Not sure if anyone does.

Thanks for the info and help... Why does msd sell 2 different coil pack control boxes if they're all the same ? I'm confused..
Nic,
Below states the reason for two different MSD controllers. In general (there are exceptions to the list below but for ease of discussion I am negating outliers)........
1997-2007 Generation III LS/VORTEC Engines, used a 24x crank reluctor (most easily identifiable by the cam sensor on the rear of the engine).
2007-Current Generation IV LS/VORTEC Engines, used a 58x crank reluctor (most easily identifiable by the cam sensor on the front of the engine in the timing cover).
As stated above, yes I know that the LS2 was available originally as a 24x engine with the Gen IV arcitechture but for the sake of this discussion I dont believe it matters. Hope this helps with confusion.

Ls, Thanks for the resources. You made my life easier..lol. Following the videos and lt1swap.com I have just completed setting up my truck harness to be a standalone set up. I found some pictures of a truck intake a guy had smoothed out and painted, So i may just try this out for the fun factor ! Thanks again..
