The harness wires from the tack goes through the fuse block into the engine harness and to the coil. They add to the efficiency and inten­sity of the spark, making the most of your new, low-resistance plug wires and fresh spark plugs. Get a modern replacement battery and at least 4-gauge cables. . I hate to see a late-model after­market stereo in the dash of a clas­sic muscle car because it just looks so incorrect. However, starter relay replacements are inexpensive and plentiful through most restoration parts houses.

Thanks much for your response and advice. Replacing them is a snap; just unbolt them from the firewall and the frame and bolt in their replacements. Often, the terminals have been overtight¬ened and distorted. Once the harness is installed, its deviations from the original design would take some seri­ous sleuthing to detect. . It is important that the repairs are per­formed correctly and are as durable as the circuit was when new, if not more durable. Lectric Limited has two series of harnesses the Original Design Series and the Custom Update Series.

I have a new engine harness. A high-performance modern electronic dis¬tributor can be a visu¬ally subtle change, but it also pays big divi¬dends in performance and convenience. Harness Replacement If the wiring harness is just too brittle, broken down, and deterio­rated to provide any more useful service, you need a replacement. This is a great choice for con­cours and stock driver restorations, as it is a harness designed with produc­tion-style components and has a very authentic appearance. Engine builders have preferences for various brands and it never hurts to hear what their recom­mendations are for your particular engine combination. Plug the terminal back in and attach the ground wire at the back of the alternator.

1966 Pontiac Lemans Alternator question

Since then, in the 60 years it has become fashionable to drive as fast as each could afford with as large engine. It doesn't show rally gauges. The wiring condition is probably a pretty good indicator of the condi­tion of the rest of the car. More spark trans­lates to a little more power, a little bet­ter fuel economy, and reduced exhaust emissions. Use a flat-head screwdriver to push against the belt. I know it has to end up there connected to the coil.

I had to do a double-take. Headlamps have prongs that fit into their sockets, while most of the rest of the bulbs use barrel-type sockets. With clear pictures, exploded view illustrations, wiring diagrams, schematics, specifications, and a list of special tools, you will have everything you need to get the job done right. I know it has to end up there connected to the coil. I like old and new, just not in some grotesque Frankendash mismatch.

Pontiac GTO Questions

Unfortunately, most of them were underpowered and overpriced junk. Ignition switches can also be problematic, and dash-mounted switches can become especially loose. Once the grounds have been attended to, it is time to move on to the other connections in the car. These tubes keep the wir¬ing dry and safe from the constant rubbing caused by passenger footwear on the carpeting. This section of the manual has 9 pages. Use new washers, remove corrosion, and clean the area to the bare metal for the best contact.

. If your wir¬ing harness has been substantially damaged, burned, or deteriorated beyond repair, you need to install a new one. Installation can be accomplished using the same procedures as for a factory-original harness. Just be sure to save the original T-3s, if they are still with the car, as they are quite valuable. Luckily the alternator seems to be operating well. Keep an eye out for obvious prob­lems like that.

Since there are still a lot of Pontiacs from this era on the road, finding replacement starters, solenoids, and accessories is pretty easy. Does anyone here know if there should be a fuse on the alternator red wire and what the correct amperage is? It also features 45 watts of power in each of its four channels and is an excellent alternative for those wishing for modern sound with an authentic look. When he told me he had a custom sound system, I asked if he hid it in the glovebox. Book cover shown in the photo is there to show which book this information came out of and is not included. If not, look for the connection failure. Sometimes, it is a simple fix, as when a wire was pulled and stretched enough that it came out of the back side of a plug-in connector.

Replace the breaker points on any street-driven restoration with an elec­tronic control module and compat­ible coil, like those from Pertronix. But if you are adding any power options, it makes sense to upgrade to a higher-amperage version. Photo Courtesy Scott Tiemann If your car has an aftermarket tach or other accessory gauges installed, the decision to retain them is based on your restoration type and their condition. Manufactured by Antique Auto Radio, this head unit fits in the stock location but is only about 3 inches deep, taking up less space than a stock radio. The harness has never been cut and came to me complete with the original wrapping and tape labeling. It is worth noting the fact that Pontiac was the first to offer customers a variety of engine options on the same machine.
