Actual wiring from car to computer is very simple. Be sure that the battery power wire can handle 30 amps. The dust cover just slides off by moving it away from the wiring harness - there is a small wiring clip that may need to be removed from the dust cover first - in my case the clip had already come loose from the harness tape, so the dust cover slid off easily. All harness connectors are clearly labeled, and each connector can fit only in the correct place. Each harness is thoroughly tested before shipping out to ensure a trouble-free conversion.
Since it is only used to turn the relays on there is less draw on the stock 30 year old scout wiring. The rest of us will stick to something we might actually find for a decent price - and we'll also continue to hate those of you who somehow manage to find a great deal on real Corvette parts. Installation is simple, there are only 4 wires which you will need to run. Other was kind of the same deal but it was in his 48caddy, no start, discovered all the injectors were plugged up. I too agree on converted stock.
These harnesses are designed for engine operation only. Can be tied with D1. If I were doing the swap I'd use the original harness too. I'm not ready to tackle that kind of fabrication, so I've pretty much resigned myself to the fact that I'm going to have to pay someone else to do it. As part of an aggressive focus on low-cost, I am attempting to build my own harness out of factory bits.
Another choice is a custom throttle body that mounts directly to the carb mounting pad and the air cleaner mounts on top, similar to a carburetor. That means I am automatically heading to the aftermarket or to a custom fabrication source for the intake manifold modifications and the matching custom fuel rails I will need. Further research indicates that they are soldered down, which makes sense given the environment they live in - lots of vibrations and heat cycles could easily cause non-soldered components to back out of their sockets and cause problems. If it's one you just removed, it may not be bent out much if at all. If you have to force it - stop and wiggle the paper clip around some more.
This is a ground to turn on the light. Make sure to measure your actual hood clearance to be sure, though. Each harness is built once ordered. Note: Picture shown is for a 90-92 Speed Density harness. Because the two vehicles I own that are most likely to get this swap done on them both use a Buick 455 and they both seem to have space for the computer in this area, so I did my diagramming with that in mind.
I also assumed the computer would mount in the driver's side fender area next to the brake booster. One idea I had would be to use spacers that would go under the existing intake manifold that would have injector bungs in them and use a throttle body on top of the original intake manifold. Pretty much everything on this website is , if you want to use something,. We choose to introduced in this article since this may be one of good reference for any tpi fuel injection wiring harness choices. It typically has a few vacuum hoses running to it as well. If you are crimping a new terminal onto a wire, you must install the correct size seal for the wire size you are using onto the wire before you install and crimp the terminal onto the wire. At this point you can remove individual terminals from the connector.
On the other hand, if you happen to come across a 1990 or 1991 Corvette you can pirate for these parts and the stuff is actually reasonably priced, then by all means, grab what you need along with the rest of the Unobtanium you find at the same time. Emissions related items are marked in purple, items for options you might not have are marked in blue, items that can be omitted if you desire not to use them are marked in green, and stuff you will likely never use is shown in red. This one ties into several places, the fuel pump, the relay, and the ecm. In theory, I could do the conversion myself, but 1 it requires welding the injector bungs to the manifold and I don't know how to weld aluminum and 2 it requires very precision machining on the fuel rails in both size and location for each injector. If you have any questions or would like to discuss other options, feel free to contact us at. It also has the potential advantage of using the same air cleaner setup you were running with your carburetor. But, since this is my page and my cars, my opinion counts for a lot no matter how biased it may be.
It's not an unreasonable request, it doesn't involve money, and it's simple to fulfill. If I choose to wire the fuel pump relay without using the oil pressure sensor, that's one more thing I don't need to hook up. You just need to make sure everything is working right. These bolts are part of special clips that slide and lock into various slots in the housing that allow for different mounting options. And if you want to see more pictures more we recommend the gallery below you can see as a reference from your Painless Tpi Wiring Harness Diagram Gm Diagrams Scematic In. I'd do the same if I used stuff from your site, and if it's extensive use, I'd ask you first. Some guys make short cuts, don't mess with perfection! There are also numbers on the plug for each pin.
